| Debugging Http or Web Services Calls from ASP.NET with Fiddler ... If you've tried to trace Http requests to Web Services or WebRequest calls in an ASP.NET application you've probably found although ASP.NET requests show up in tools like Fiddler or Charles, but the Web Service or WebRequest/WebClient calls do not. You can make this work however by modifying the proxy settings in web.config explicitly. | Go |

The TOC is going to be rendered as either a <ul> or <ol> html list of anchors (links) to the corresponding heading tags. If the post or page is being saved for the first time then the TOC will be placed where the tag [ t o c a u t o g e n ] is located. Updating the post will look for <div id="tocautogen"></div> html construct and it replace it with the updated version of the TOC. The html that renders the TOC uses the xoxo class id pattern that specifies the Microformats XOXO Outline. | Go |

| ASP.NET MVC: Securing Your Controller Actions (My Way) ... So I just read Rob Conery's blog post on Securing Your Controller Actions in MVC. I was a little perplexed about why guys at Microsoft love to reinvent stuff they have already done. I know Rob Conery is a really smart guy and has a wonderful grasp of the .NET framework, so I would have to assume he knows about what I have outlined below. My only guess is that he just wanted to re-invent something that is already built in to the framework using his own code. I personally prefer the PrincipalPermissionAttribute which has been part of the .NET framework since 1.0 and implements the CodeAccessSecurityAttribute which is used by the run time. | Go |

| March 14th Links: ASP.NET, ASP.NET AJAX, ASP.NET MVC and .NET ... I'm slowly recovering from keynoting at MIX last week, and have been digging my way out of backlogged email the last few days. I'm going to try and finish catching up on blog comments this weekend - apologies for the delay in getting back to some of your questions. To kick-start my blogging again I thought I'd post a new link-listing series . Today's post is mostly focused on ASP.NET and web related links. I'm going to be doing more Silverlight and WPF posts soon. ASP.NET Tag Cloud Filters with ASP.NET 3.5's LinqDataSource and ListView Controls : Matt Berseth has a cool post that shows off using LINQ to SQL and ASP.NET 3.5 to build a tag-cloud navigation UI. Five New ASP.NET Security Tutorials Now Available : Scott Mitchell continues his great ASP.NET security tutorials . These 5 new ones (all in both VB and C#) cover using the ASP.NET membership system. Building a Vista Style Folder Browser with ASP.NET 3.5 and a Custom Hierarchical DataSource Control: Matt Berseth continues his great posts with a nice one that shows how to build a custom HierarchicalDataSourceControl to implement file browsing functionality using ASP.NET. ASP.NET AJAX New ASP.NET AJAX Control Toolkit Release: David Anson blogs about a new ASP.NET AJAX Control Toolkit release that the team made right before MIX.

| My Presentations in Arizona this Tuesday ... This week I'm visiting Scottsdale Arizona and will be presenting at a free user group event during the day. I'm presenting two sessions myself: 1) Developing Applications using Silverlight 2 : This will be a drill-down into the new Silverlight 2 Beta1 release, and how you can build applications with it using VS 2008 and Expression Blend. You'll leave this session with a good understanding of the basics of Silverlight programming and how to start building applications with it. 2) Developing Applications using ASP.NET MVC : This session will be a drill-down into the new ASP.NET Model-View-Controller framework option (which last week was updated . You'll leave this session with a good understanding of what it is, how it works, and how to start building ASP.NET web applications with it.

| First Look at Using Expression Blend with Silverlight 2 ... Last week I did a First Look at Silverlight 2 post that talked about the upcoming Silverlight 2 Beta1 release. In the post I linked to some end-to-end tutorials I've written that walk through some of the fundamental programming concepts behind Silverlight and WPF, and demonstrate how to use them to build a "Digg Search Client" application using Silverlight: Part 1: Creating "Hello World" with Silverlight 2 and VS 2008 Part 2: Using Layout Management Part 3: Using Networking to Retrieve Data and Populate a DataGrid Part 4: Using Style Elements to Better Encapsulate Look and Feel Part 5: Using the ListBox and DataBinding to Display List Data Part 6: Using User Controls to Implement Master/Details Scenarios Part 7: Using Templates to Customize Control Look and Feel Part 8: Creating a Digg Desktop Version of our Application using WPF In this first set of Silverlight tutorials I didn't use a visual design tool to build the UI, and instead focused on showing the underlying XAML UI markup (which I think helps to explain the core programming concepts better). Now that we've finished covering the basics - let's explore some of the tools we can use to be even more productive. Expression Blend Support for Silverlight In addition to releasing the upcoming Beta1 of Silverlight 2, we are also going to ship Visual Studio 2008 and Expression Studio tool support for targeting it. These tools will offer a ton of power for building RIA solutions, and are designed to enable developers and designers to easily work on projects together. In today's post I'm going to introduce some of the features in the upcoming Expression Blend 2.5 March preview. After demonstrating some of the basics of how Blend works, we are going to use it to build a cross-platform, cross-browser Silverlight IM chat client: The above screen-shot shows what the application looks like at runtime on a Mac. Below is a screen-shot of what it looks like at design-time within Expression Blend: We'll use Expression Blend to graphically construct all of the UI for the application, as well as use it to cleanly data-bind the UI to .NET classes that represent our chat session and chat messages. All of the controls we'll use to build the chat application are built into Beta1 of Silverlight 2. Disclaimer: I am not a designer (nor am I cool) Let me say up front that I am a developer and not a designer. I'm also not very cool. While I understand the techniques to create UI, I sometimes choose bad colors and fonts when putting it together (only after I did all the screen-shots for this post did a co-worker helpfully point out that there is actually a site dedicated to banning some of the fonts and colors I used . Ouch). For those of you with artistic skill out there - please be gentle with me and focus your attention on the features and techniques I demonstrate below, rather than on the font and color choices I use. :-) Getting Started: Creating a new Silverlight 2 Project Expression Blend and Visual Studio 2008 share the same solution/project file format, which means that you can create a new Silverlight project in VS 2008 and then open it in Expression Blend, or you can create a new Silverlight project in Expression Blend and open it in VS. You can also have both Expression Blend and VS 2008 open and editing the same project as the same time. Since in my previous Silverlight tutorial series I already showed how to create a new Silverlight project using VS 2008, let's use this post to show how to create a new Silverlight application using Expression Blend. To do this, simply choose File->New Project in Expression Blend, select the "Silverlight 2 Application" icon, and click ok: This will create a new (VS-compatible) solution file and Silverlight application project: Blend includes a full WYSIWYG designer for Silverlight 2 applications. When opening Silverlight pages and controls you can switch the design-surface to be in design vie | Go |
| First Look at Silverlight 2 ... Last September we shipped Silverlight 1.0 for Mac and Windows , and announced our plans to deliver Silverlight on Linux. Silverlight 1.0 focused on enabling rich media scenarios in a browser, and supports a JavaScript/AJAX programming model.
We are shortly going to release the first public beta of Silverlight 2, which will be a major update of Silverlight that focuses on enabling Rich Internet Application (RIA) development. This is the first of several blog posts I'll be doing over the weeks and months ahead that talk in more depth about it.
Cross Platform / Cross Browser .NET Development
Silverlight 2 includes a cross-platform, cross-browser version of the .NET Framework, and enables a rich .NET development platform that runs in the browser. Developers can write Silverlight applications using any .NET language (including VB, C#, JavaScript, IronPython and IronRuby). We will ship Visual Studio 2008 and Expression Studio tool support that enables great developer / designer workflow and integration when building Silverlight applications.
This upcoming Beta1 release of Silverlight 2 provides a rich set of features for RIA application development. These include:
WPF UI Framework : Silverlight 2 includes a rich WPF-based UI framework that makes building rich Web applications much easier. In includes a powerful graphics and animation engine, as well as rich support for higher-level UI capabilities like controls, layout management, data-binding, styles, and template skinning. The WPF UI Framework in Silverlight is a compatible subset of the WPF UI Framework features in the full .NET Framework, and enables developers to re-use skills, controls, code and content to build both rich cross browser web applications, as well as rich desktop Windows applications.
Rich Controls : Silverlight 2 includes a rich set of built-in controls that developers and designers can use to quickly build applications. This upcoming Beta1 release includes core form controls (TextBox, CheckBox, RadioButton, etc), built-in layout management panels (StackPanel, Grid, Panel, etc), common functionality controls (Slider, ScrollViewer, Calendar, DatePicker, etc), and data manipulation controls (DataGrid, ListBox, etc). The built-in controls support a rich control templating model, which enables developers and designers to collaborate together to build highly polished solutions.
Rich Networking Support : Silverlight 2 includes rich networking support. It includes out of the box support for calling REST, WS*/SOAP, POX, RSS, and standard HTTP services. It supports cross domain network access (enabling Silverlight clients to directly access resources and data from resources on the web). Beta1 also includes built-in sockets networking support.
Rich Base Class Library : Silverlight 2 includes a rich .NET base class library of functionality (collections, IO, generics, threading, globalization, XML, local storage, etc). It includes rich APIs that enable HTML DOM/JavaScript integration with .NET code. It also includes LINQ and LINQ to XML library support (enabling easy transformation and querying of data), as well as local data caching and storage support. The .NET APIs in Silverlight are a compatible subset of the full .NET Framework.
Silverlight 2 does not require the .NET Framework to be installed on a computer in order to run. The Silverlight setup download includes everything necessary to enable all the above features (and more we'll be talking about shortly) on a vanilla Mac OSX or Windows machine.
The Beta1 release of Silverlight 2 is 4.3MB in size, and takes 4-10 seconds to install on a machine that doesn't already have it. Once Silverlight 2 is installed you can browse the Web and automatically run rich Silverlight applications within your browser of choice (IE, FireFox, Safari, etc).

| .NET 3.5 Client Product Roadmap ... A few months ago I did a .NET Web Product Roadmap blog post where I outlined some of the product plans we have to build on top of the web development features we’ve shipped with Visual Studio 2008 and .NET 3.5. Over the next few months we will also be releasing a number of enhancements specific to client development as well. We have put a lot of effort into addressing some of the biggest areas of customer feedback, while also trying to really push the envelope on the capabilities developers have when building Windows applications. All of these improvements build on top of VS 2008 and .NET 3.5, and will make .NET client development even better going forward. Below is a roadmap of some of the upcoming releases we have planned for the months ahead: Improved .NET Framework Setup for Client Applications One of the biggest asks we’ve had over the years from customers and ISVs building client applications is to make the setup and installation of the .NET Framework easier and faster. This summer we are going to ship a new setup framework for .NET that makes it easier to build optimized setup packages for client applications. This setup framework can be integrated with existing installation frameworks (for example: products like InstallShield), and enables a smaller and faster end-user setup experience of the .NET Framework. Windows Forms and WPF client applications will be able to use this setup framework to cleanly “bootstrap” getting the .NET Framework installed onto machines. The setup “bootstrap” utility will support automatically downloading the minimal set of .NET Framework packages needed to enable .NET 3.5 client applications on a machine. For example, if a user already has .NET 2.0 installed on their machine, setup will be smart enough to automatically download only the upgrade patches necessary to update .NET 2.0 to 3.5 (and not have to re-download the components already provided by .NET 2.0). This will significantly shrink the payload size of client setup programs, and speed up the installation experience. We’ll also be delivering improvements that enable a more integrated application install experience for both MSI and ClickOnce based solutions, and support a more consumer friendly user experience that is easy to build. Improved Working Set and Startup Improvements for .NET Client Applications One of the other common asks we receive is to enable .NET client applications to launch faster in “cold startup” scenarios. “Cold startup” scenarios occur when no other .NET client applications are running (or have recently run) on a machine, and require the OS to load lots of pages (code, static data, registry, etc) from disk. If you are loading a large .NET client application or library, or are using a slow disk, these cold startup scenarios can require many seconds for your application to start. This summer we are going to ship a servicing update to the CLR that makes some significant internal optimizations in how we optimize our data structures to cut down on disk IO and improve memory layout when loading and running applications. Among many other benefits, this work will significantly improve the working set and cold startup performance of .NET 2.0, 3.0 and 3.5 applications and will dramatically improve end-user experiences with .NET-based client applications. Depending on the size of the application, we expect .NET applications to realize a cold startup performance improvement of between 25-40%. Applications do not need to change any code, nor be recompiled, in order to take advantage of these improvements so the benefits are automatic. WPF Performance Improvements This summer we are also planning to release a servicing update to WPF that includes a bunch of performance optimizations that improve its text, graphics, media and data stack. These include: - Moving the DropShadow and Blur bitmap effects, which are currently software rendered, to be hardware acc | Go |
| Feb 17th Links: ASP.NET, ASP.NET AJAX, Visual Studio, .NET ... Here is the latest in my link-listing series . Also check out my ASP.NET Tips, Tricks and Tutorials page for links to popular articles I've done myself in the past. ASP.NET Top 10 Best Practices for Production ASP.NET Applications : Kyle has a nice post that summarizes a number of good best practices to follow when deploying your ASP.NET applications into production. Paging Through Data with the ASP.NET 3.5 ListView and DataPager Controls : Scott Mitchell continues his excellent series on the new ASP.NET 3.5 data control features. In this latest article he shows how to page using the ListView and DataPager controls. ASP.NET AJAX How to install and use the ASP.NET AJAX Control Toolkit in VS : Nannette Thacker has a nice post that details step-by-step how to install and use the ASP.NET AJAX Control Toolkit controls within Visual Studio or Visual Web Developer. JavaScript Stack Traces in ASP.NET AJAX and JavaScript Error Publishing using ASP.NET AJAX : Joel Rumerman has put together two nice posts that detail some god ways to capture JavaScript stack trace information, as well as to report JavaScript errors using ASP.NET AJAX. ASP.NET AJAX History Tutorials : Jonathan Carter has published a good series of tutorials that demonstrate how to use the new ASP.NET AJAX History support that we'll be shipping later this year (it is currently available in the ASP.NET Extensions CTP download). This enables you to add forward/back button navigation support within AJAX applications. Using JQuery with VS 2008 JavaScript Intellisense : One of the improvements we shipped in our recent VS 2008 Hotfix Roll-Up last week was to address issues with JavaScript intellisense support for JQuery (another popular AJAX framework). Brennan Stehling, James Hart, and Lance Fisher have done blog posts recently that discuss how to enable even richer JQuery intellisense inside VS 2008 using intellisense-friendly JQuery libraries that are referenced while coding (and then swapped out for the real library at runtime). You can read their blog posts about how this works here and here and here . ASP.NET MVC Tip: Submitting an AJAX Form with JQuery : While on the subject of JQuery, I thought I'd link to a post in Mike Bosch's ASP.NET MVC series that shows how you can integrate JQuery in the browser on the client with the ASP.NET MVC framework on the server. Visual Studio Visual Studio Programmer Themes Gallery: Visual Studio enables you to customize the color settings of the text editor and IDE, as well as to export and import the settings (use the Tools->Import and Export Settings menu to do this). Scott Hanselman has a great post that provides previews of a bunch of cool pre-built themes that people have published that you can download and use for free. Did you know: the Solution Explorer Supports Type-Ahead Selection : Sara Ford has another nice post in her series on Visual Studio tips and tricks. This post talks about a shortcut you can use to quickly select files in the solution explorer. Code Profiler Analysis in VS 2008 : Maarten Balliauw has a nice post that describes how to use the code profiling features in the Developer edition of Visual Studio Team System to analyze code performance. Visual Studio Team System 2008 Database Edition Power Tools : Greg Duncan posts about the new power tools download that has been released by Microsoft and which delivers a bunch of cool new database development features for the Database editions of Visual Studio Team System. Japanese Release of VS 2008 Web Deployment Projects : Late last month I announced the release of the VS 2008 Web Deployment Project support. This past week the team also released a localized Japanese version of it. Note: you can read a Japanese translated version of my blog here (thanks Chica!). .NET LINQ to JSON , LINQ to SharePoint , LINQ to Active Directory , LINQ to TerraServer , LINQ to FlickR : Just a few of the new LINQ providers now available | Go |
| ASP.NET MVC Framework Road-Map Update ... This past December we released the first preview of a new ASP.NET MVC Framework as part of the ASP.NET 3.5 Extensions CTP Release . I also wrote a number of blog posts that provide more detail on what the ASP.NET MVC framework is and how you can optionally use it: Introducing the ASP.NET MVC Framework ASP.NET MVC Tutorial (Part 1) ASP.NET MVC Tutorial (Part 2: Url Routing) ASP.NET MVC Tutorial (Part 3: Passing ViewData from Controllers to Views) ASP.NET MVC Tutorial (Part 4: Handling Form Edit and Post Scenarios) We've had great feedback on the framework since then, and had a ton of downloads and excitement around it. One of the common questions people have asked me recently is "when will a new build be released and what will be in it?". The below post provides a few updates on what the ASP.NET MVC feature team has been working on, and some of the new features that will be available soon. I'm going to do a separate blog post in the future that will cover the new ASP.NET Dynamic Data and ASP.NET AJAX feature work that is progressing along nicely as well. All of these features (ASP.NET MVC, ASP.NET Dynamic Data, and the new ASP.NET AJAX improvements) will ship later this year and work with VS 2008 and .NET 3.5. Upcoming ASP.NET MVC MIX Preview Release We are planning to release the next public preview of ASP.NET MVC at the MIX 08 conference in a few weeks. This build will be available for anyone on the web to download (you do not need to attend MIX to get it). We have incorporated a lot of early adopter feedback into this release. Below are some of the improvements that will appear with this next preview release: 1) The ASP.NET MVC Framework can be deployed in the \bin directory of an app and work in partial trust The first ASP.NET MVC preview release required a setup program to be run on machines in order for the System.Web.Mvc.dll assembly to be registered in the machine's GAC (global assembly cache). Starting with this upcoming preview release we will enable applications to instead directly reference the System.Web.Mvc.dll assembly from the application's \bin directory. This means that no setup programs need to be run on a sever to use the ASP.NET MVC Framework - you can instead just copy your application onto a remote ASP.NET server and have it run (no registration or extra configuration steps required). We are also doing work to enable the ASP.NET MVC framework to run in "partial/medium trust" hosting scenarios. This will enable you to use it with low-cost shared hosting accounts - without requiring the hosting provider to-do anything to enable it (just FTP your application up and and it will be good to run - they don't need to install anything). 2) Significantly enhanced routing features and infrastructure One of the most powerful features of the ASP.NET MVC framework is its URL routing engine (I covered some of these features here ). This upcoming ASP.NET MVC preview release contains even more URL routing features and enhancements. You can now use named routes (enabling explicit referencing of route rules), use flexible routing wildcard rules (enabling custom CMS based urls), and derive and declare custom route rules (enabling scenarios like REST resources mappings, etc). We have also factored out the URL routing infrastructure from the rest of the MVC framework with this preview, which enables us to use it for other non-MVC features in ASP.NET (including ASP.NET Dynamic Data and ASP.NET Web Forms). 3) Improved VS 2008 Tool Support The first ASP.NET MVC preview had only minimal VS 2008 support (basically just simple project template support). This upcoming ASP.NET MVC preview release will ship with improved VS 2008 integration. This includes better project item templates, automatic project default settings, etc. We are also adding a built-in "Test Framework" wizard that will automatically run when you create a new ASP.NET MVC Project via the File->New Pr | Go |
| VS 2008 Web Development Hot-Fix Roll-Up Available ... One of the things we are trying to do with VS 2008 is to more frequently release public patches that roll-up bug-fixes of commonly reported problems. Today we are shipping a hot-fix roll-up that addresses several issues that we've seen reported with VS 2008 and Visual Web Developer Express 2008 web scenarios. Hot Fix Details You can download this hot-fix roll-up for free here (it is a 2.6MB download). Below is a list of the issues it fixes: HTML Source view performance Source editor freezes for a few seconds when typing in a page with a custom control that has more than two levels of sub-properties. “View Code” right-click context menu command takes a long time to appear with web application projects. Visual Studio has very slow behavior when opening large HTML documents. Visual Studio has responsiveness issues when working with big HTML files with certain markup. The Tab/Shift-Tab (Indent/Un-indent) operation is slow with large HTML selections. Design view performance Slow typing in design view with certain page markup configurations. HTML editing Quotes are not inserted after Class or CssClass attribute even when the option is enabled. Visual Studio crashes when ServiceReference element points back to the current web page. JavaScript editing When opening a JavaScript file, colorization of the client script is sometimes delayed several seconds. JavaScript IntelliSense does not work if an empty string property is encountered before the current line of editing. JavaScript IntelliSense does not work when jQuery is used. Web Site build performance Build is very slow when Bin folder contains large number of assemblies and .refresh files with web-site projects. Installation Notes For more information on how to download and install the above patch, please read this blog post here . In particular, if you are using Windows Vista with UAC enabled, make sure to extract the patch to a directory other than "c:\" (otherwise you'll see an access denied error). To verify that this hot-fix patch successfully installed, launch VS 2008 and select the Help->About menu item. Make sure that there is an entry that says ‘Hotfix for Microsoft Visual Studio Team System 2008 Team Suite – ENU (KB946581)’. If you ever want to remove the patch, go to Control Panel -> Add/Remove Programs and select “Hotfix for Microsoft Visual Studio 2008 – KB946581” under Microsoft Visual Studio 2008 (or Visual Web Developer Express 2008) and click “Remove". Summary Obviously it goes without saying that we would have liked to have shipped without any bugs. Hopefully this hot-fix enables you to quickly solve them if you are encountering them. Thank you to those who helped us identify the causes of these issues, as well as to the group of customers who have helped us verify the above fixes the last few weeks. Note: If you do encounter issues with VS 2008 features for web development in the future, I recommend always asking for help in the VS 2008 Forum on www.asp.net . The VS Web Tools team actively monitors this forum and can provide help. Hope this helps, Scott | Go |

For even more ASP.NET Security Information, please check out the security tutorials I've also done on my ASP.NET Tips, Tricks and Tutorials page . 10 ASP.NET Performance and Scalability Secrets : Omar Al Zabir, the CTO and co-founder of www.pageflakes.com (a Web 2.0 portal site built with ASP.NET), has written another in his excellent series of articles on ASP.NET and ASP.NET AJAX. This article discusses tips and tricks to maximize ASP.NET performance and scalability. To learn even more about how to build great sites using ASP.NET and ASP.NET AJAX, make sure to read Omar's excellent new Building a Web 2.0 Portal with ASP.NET 3.5 book. .NET Debugging Demos Lab : Tess Ferrandez, who is an ASP.NET escalation engineer for Microsoft support and who also posts incredible articles on the art of debugging production ASP.NET applications, has started a new tutorial series that provides a sample "buggy" application and a series of questions/problems you can work through to learn how to debug problem applications in production environments. 4 Alternative View Engines for ASP.NET MVC : The open source MvcContrib project has been adding lots of cool goodness on top of the ASP.NET MVC Framework. Jeffrey Palermo posts about 4 alternative view rendering engines now in the project that you can use if you don't want to use the default .aspx based view engine. BTW - I'll be doing a new post on ASP.NET MVC within the next week talking about some of the cool new features coming soon with the next refresh. ASP.NET AJAX Boost ASP.NET Performance with Deferred Content Loading : Dave Ward continues his great articles on ASP.NET AJAX. This article talks about how you can improve the perceived load-time of a page by using an AJAX callback to retrieve HTML content once the page loads on the client. This approach is similar to the one I wrote about in my tip/trick post here . Build Yahoo UI Style Glowing Buttons with the ASP.NET AJAX Control Toolkit GlowButtonExtender Control: Matt Berseth continues his excellent series on using ASP.NET AJAX. In this post he discusses how to create cool glowing button effects. Visual Studio Resolving Namespaces and Removing Unused Using Statements : David Hayden has a nice article that discusses a few Visual Studio code editing features that developers often overlook. Visual Studio 2008 Product Comparison : Several people have sent me email in the past asking for a page that describes the differences between the various Visual Studio 2008 editions (Standard, Professional, Visual Studio Team System, etc). This link is useful to bookmark if you want to learn more about this. Did you know...You can Shift+ESC to close a tool window: Sara Ford continues her excellent "Did you know..." VS 2008 tips and tricks series. I confess I didn't know this one. One productivity tip I always recommend is to really learn the keyboard shortcuts of your development tool environment well - since using them over time can yield significant productivity savings. Click here to download a VB 2008 key bindings poster, or click here to download the C# 2008 key bindings poster equivalent. Print them out and put them under your pillow to absorb them while you sleep. .NET The Power of Yield : Joshua Flanagan has a nice article on one of the coolest, yet underused, feature of C# in .NET 2.0 | Go |
| MIX08 ... MIX is a Microsoft web development conference we hold in Las Vegas each year. MIX tends to be a pretty fun event, both because it covers cutting edge content (we used MIX07 to announce our Silverlight plans), and also because it tends to attract a really diverse set of attendees (including both those who use Microsoft technology today, and a large % of attendees who don't). The conference structure includes a healthy blend of sessions and interactive panels, and the layout and organization is designed to facilitate great conversations. This year's MIX is being held March 5th-7th in Las Vegas. Ray Ozzie and I are both giving keynotes the first day of the event, and Steve Ballmer and Guy Kawasaki will be doing a keynote the second day of the event. The conference (and especially my keynote) is going to cover a lot of new web technology. Attendees will be able to attend sessions covering: IE 8 IIS 7.0 ASP.NET (including ASP.NET 3.5, ASP.NET AJAX, ASP.NET MVC, and ASP.NET Dynamic Data) VS 2008 and Expression Studio WPF Silverlight 2 And much more.... Channel 9 recently did an interview with me where I talked about some of these new technologies. In Part 1 of the interview I talked about IIS7, and in Part 2 of the interview I talked about ASP.NET, WPF and Silverlight 2. Register Soon Or You'll Miss Your Chance MIX is held at a smaller venue then some of our larger events like TechEd and PDC. This gives the conference a more intimate feel (which is fun). It also means that it sells out each year, and once it is sold out it is really sold out. Last year I received about 50 emails from people begging for tickets after it was full, and many people even flew to the event hoping to somehow be let in at the door (only to be unfortunately told they couldn't get in). Unfortunately because of size constraints (and fire marshal restrictions) once it is sold out there really are no more tickets to be had. Even my own team members get turned away if they haven't registered in time. This year's registration is filling up faster than any of the previous MIX conferences. If you want to attend I highly recommend registering really soon to ensure you can go. You can learn more about the event and register online here . Hope to see some of you there - it is going to be fun.... Scott | Go |
| VS 2008 Web Deployment Project Support Released ... This past Friday we released the final RTW (release to web) support for VS 2008 Web Deployment projects. You can learn more about it and download it for free here . Web Deployment projects can be used with either the "ASP.NET Web Site" or "ASP.NET Web Application Project" options built-into VS 2008, and provide a few additional build, packaging and deployment options for you to use. You can read an old tutorial post of mine here to learn more about they work. The VS 2008 Web Deployment Project version supports all of the existing features provided by the VS 2005 web deployment download. It also adds additional support for: Easily migrating VS 2005 Web Deployment Projects to VS 2008 Web Deployment Projects Replacing output only if web deployment builds succeed IIS7 Support This RTW (release to web) version fixes bugs and adds some small features that people requested in the December CTP version we released last month. Please make sure to run setup and uninstall any older version of the VS 2008 Web Deployment Project support you have installed before installing this final version. VS 2008 Web Deployment Projects can be installed side-by-side with VS 2005 Web Deployment Projects - so there is no need to uninstall the VS 2005 version if you are still using it with older projects. More Deployment Features In my last link-listing post I pointed at the new Web Deployment Tool being released by the IIS team. This tool works with both IIS6 and IIS7 and enables automated copy deployment, file synchronization, and migrating of applications onto web servers. If you are looking for a great way to automate the deployment of your ASP.NET applications onto remote servers then this tool is definitely one to check out. You can use VS 2008 Web Deployment Projects as a post-build step within your build environment to fix up last minute deployment settings - and then use the IIS Web Deployment tool to copy them remotely onto server machines. Alternatively you can also use the IIS Web Deployment Tool to copy vanilla "ASP.NET Web Site" or "ASP.NET Web Application" projects to remote machines (no VS 2008 Web Deployment Project required). To learn more about the new IIS Web Deployment tool, read the walkthroughs at the bottom of this page (in particular the "Introduction to MS Deploy" one). I will also be doing a blog post in the future that talks more about how to use it to automate your web server deployments. Hope this helps, Scott | Go |
| Jan 24th Links: ASP.NET, ASP.NET AJAX, Visual Studio, .NET, IIS ... I just arrived back from my trip from Asia, and decided to celebrate (since I'm jet-lagged and can't sleep) with a new post in my link-listing series . You can check out my ASP.NET Tips, Tricks and Tutorials page for links to popular articles I've done myself in the past. ASP.NET Extending the GridView to Include Sort Arrows : Scott Mitchell has a nice article that describes how to add a visual indicator to the GridView control to indicate the current sort order on columns. Using ASP.NET 3.5's ListView and DataPager Controls: Sorting Data : Scott Mitchell continues his ListView control series with a good article on enabling sorting scenarios with the new ListView control. Building a Grouping Grid with the ListView and LinqDataSource Controls : Matt Berseth has an awesome post that shows off using the new ListView control and LinqDataSource controls to build a hierarchical grouping grid. A post to bookmark. Using the ListView, DataPager and LinqDataSource Controls : Matt Berseth has a good tutorial post that shows off using these new controls to join data from two database tables using LINQ. Some ASP.NET 3.5 ListView Control Examples : Mike Ormond has a nice post that provides a number of samples that show how to use the new ASP.NET ListView control. For even more ListView articles, check out my last link-listing post which pointed to a bunch of them. Large File Uploads in ASP.NET : Jon Galloway has a nice post that provides some good details on handing large file uploads using ASP.NET. ASP.NET AJAX Four ASP.NET AJAX JavaScript UI Methods You Should Learn : Dave Ward has another great post in his series about ASP.NET AJAX's client-side JavaScript Helper Methods . Five Tab Themes Created for the ASP.NET AJAX Control Toolkit : Matt Berseth posts some really cool themes created for the ASP.NET AJAX Control Toolkit's Tab control. Very slick! CNN Style Scrolling Ticker with the Marquee Toolkit Control : Matt Berseth posts another great one that shows how to implement a scrolling marquee UI using the ASP.NET AJAX Control Toolkit. Visual Studio Did You Know?: Lisa Feigenbaum from the VB team has posted a really cool series of blog posts that talk about some of the new VS 2008 editor and IDE features. Read Part 1: Intellisense Everywhere , Part 2: IntelliSense is now Transparent , Part 3: Ctrl+Tab to Navigate Windows , Part 4: What You Can Do with Debugger DataTips , and Part 5: VB IntelliSense now filters as you type . Web Server Settings for ASP.NET Web Application Projects can now be stored per user as well as per project : The VS Web Tools Team has a nice post that describes how you can now store web server settings per-user instead of per-project. This is very useful for multi-developer scenarios (where you don't want to check-in these values into source control). Using Ctrl-Break to Stop VS Building : Steven Harman points out a cool tip/trick, which is that you can use the Ctrl-Break key within Visual Studio to kill the current compilation build. A useful tip if you've accidentally kicked off a long build or get tired waiting for it to finish. Visual Studio 2008 Trouble Shooting Guide : If you run into any issues installing VS 2008, make sure to check out this blog post. It details a bunch of common causes of failures, and how to fix them. .NET Marshaling between Managed and Unmanaged Code : Yi Zhang and Xiaoying Guo from my team in Shanghai have written a great MSDN article that describes how to use the marshaling interop features of the CLR to call native code. One of the tools they highlight is an awesome P/Invoke Interop Assistant application they built that makes it much, much easier to generate p/invoke interop signatures when calling native methods. A must-have tool for anyone doing native/managed interop! .NET Framework 3.5 Poster : Brad Abrams posts about the cool new .NET Framework 3.5 posters now available for download (now in multiple file formats).

| .NET Framework Library Source Code now available ... Last October I blogged about our plan to release the source code to the .NET Framework libraries , and enable debugging support of them with Visual Studio 2008. Today I'm happy to announce that this is now available for everyone to use. Specifically, you can now browse and debug the source code for the following .NET Framework libraries: .NET Base Class Libraries (including System, System.CodeDom, System.Collections, System.ComponentModel, System.Diagnostics, System.Drawing, System.Globalization, System.IO, System.Net, System.Reflection, System.Runtime, System.Security, System.Text, System.Threading, etc). ASP.NET (System.Web, System.Web.Extensions) Windows Forms (System.Windows.Forms) Windows Presentation Foundation (System.Windows) ADO.NET and XML (System.Data and System.Xml) We are in the process of adding additional framework libraries (including LINQ, WCF and Workflow) to the above list. I'll blog details on them as they become available in the weeks and months ahead. Enabling Reference Source Access in Visual Studio 2008 Enabling .NET Framework source access within Visual Studio 2008 only takes a few minutes to setup. Shawn Burke has a detailed blog post that covers the exact steps on how to enable this in more depth here . If you run into problems or have questions setting it up, please post a question in the Reference Source Forum on MSDN here . Stepping into .NET Framework Library Source Once you follow the configuration steps in Shawn’s post above, you’ll be able to dynamically load the debug symbols for .NET Framework libraries and step into the source code. VS 2008 will download both the symbols and source files on demand from the MSDN reference servers as you debug throughout the framework code: Developer comments are included in the source files. Above you can see an example of one in the Dispose method for the Control base class. Sometimes you'll see comments that reference a past bug/tracking number in our bug/work-item tracking database that provides additional history about a particular code decision. For example, the comment above calls out that a particular field shouldn't be nulled to maintain backwards compatibility with an older release of the framework, and points to a backwards compatibility bug that was fixed because of this. Reference License The .NET Framework source is being released under a read-only reference license. When we announced that we were releasing the source back in October, some people had concerns about the potential impact of their viewing the source. To help clarify and address these concerns, we made a small change to the license to specifically call out that the license does not apply to users developing software for a non-Windows platform that has “the same or substantially the same features or functionality” as the .NET Framework. If the software you are developing is for Windows platforms, you can look at the code, even if that software has "the same or substantially the same features or functionality" as the .NET Framework. Summary We think that enabling source code access and debugger integration of the .NET Framework libraries is going to be really valuable for .NET developers. Being able to step through and review the source should provide much better insight into how the .NET Framework libraries are implemented, and in turn enable you to build better applications and make even better use of them. Hope this helps, Scott | Go |
| Visiting China, South Korea and Japan the Next Two Weeks ... This Friday I'm leaving for a 10 day trip to Asia. Traveling on business doesn't usually get me excited (I was on a plane ~70 times last year), but I am really looking forward to this trip as it will be my first trip to Asia. I'll be visiting China (Beijing, Shanghai, Shenzhen), South Korea (Seoul), and Japan (Tokyo), and I will be presenting at events, meeting with customers, and visiting one of the development teams in my group that is based in China. I'm also hoping to get a chance to see immerse myself a little in the countries. Below are some details on the presentations I'll be doing during the trip if you are interested in attending or learning more: China (Beijing, January 13th) China (Shanghai, January 14th) <= Update South Korea (Coex Conference Center 310 on January 17th) Japan (Izumi Garden Gallery in Roppongi, Tokyo on January 21st) I've been extremely fortunate the last year to have had some great people volunteer to translate my blog posts into other languages (including Chinese and Japanese). Below are links to a few of the feeds if English isn't your first language: My Blog Posts in Chinese My Blog Posts in Japanese My Blog Posts in Spanish I'm hoping to meet Xuegen Jin (who has been translating my posts to Chinese and hosting them on HongChao Wang's site) and Chica (who has been translating my posts into Japanese) on the trip and have the chance to thank them personally. :-) Thanks, Scott | Go |

| ASP.NET MVC and IE8 WebActivities ... One of the great things in readify is the ability to do Professional Development at scheduled intervals to keep up to speed with the latest industry technologies and advancements. My latest foray into this (amongst other things) has been looking at the ASP.NET MVC framework and Internet Explorer 8 WebActivities . Both of these technologies are quite cool and I wanted a way to learn about them both and link them in some way where I could learn about them at the same time. To that end, I created a solution in Visual Studio 2008 which utilises the ASP.NET MVC framework and allows a user to enter some fields to create an IE8 Web Activity definition. You can then view the XML definition, and click the 'Add' button to add that activity to Internet Explorer 8 as a proper web activity. The web activity generated is not particularly functional, but does allow previews, icon definition, execute actions, however has no current support for parameters. Again, not really intended as a fully fledged utility or application, but a good way to learn about both the MVC framework and IE8 activities. The solution can be downloaded here . Obviously, you need Visual Studio 2008, the ASP.NET MVC preview 2 framework , and have Internet Explorer 8 beta installed. Feel free to download, play, chop up etc...

| Anti-agile hatemail ... Today I received through the contact form on this blog a hate-mail from a guy who called himself 'Ryan'. Ryan used a fake, non-existing email address so the only way to respond to him is via my blog, hence this post. Let's look at the email first:
From: ryan@notanoob.org
Subject: (Frans Bouma's blog) : anti-agile
Your post on Jeffrey Palmero's blog is laughable. He is a smart and successful person and is involved in practices that you do not understand. Your post makes you look like a moron. You obviously have a lot to learn about agile development.
The ONLY thing that works on large .net projects is the platform independent knowledge that the java / C++ / small talk community has learned over the past 20 years. I know because I work on a 3 million LOC, 200+assembly .net product every day. MS built the best development platform, but what MS teaches is crap. In the end, the culture of the development shop is what makes or breaks it. Agile practices focus on that culture. Tools and processes are secondary.
One day when you work on a real app that is more than 100K lines of code maybe you'll understand. You should not venture outside of the realm of your fan base, which is newbie developers that have a background in ASP.
I would love to see your product choke on several of our 100+GB databases.
Thanks.
My post about stored procedures back in 2003 generated the fair share of hate-mail in which angry DBAs and other stored procedure supporters wished me all kind of bad things and told me I had no clue whatsoever. I think it's related to speaking up in public and some people apparently can't deal with another person's opinion very well.
This particular email illustrates something I can't understand: why does someone get so angry about a random reply I've written to someone's weblog that that person goes to this particular blog, and types in the text above? What's the goal? To tell me how the world really works? It's never a pleasure receiving this kind of email, and it surprises me every time why a person thinks 10 minutes of his/her precious time is better spend on writing a hate mail than writing a mail which could open up a mature discussion so ideas/thoughts/arguments can be exchanged and both parties participating in the discussion can learn from eachother.
Let's address the various topics which are mentioned in the email. To start, I have no idea who this 'Ryan' person is, and I definitely don't know which post on Jeffrey's blog he's referring to. I don't doubt Jeffrey is smart and succesful, and I have no problem whatsoever with Jeffrey at all. Too bad Ryan didn't include a link so I could have elaborated what I wrote.
Ryan then goes into show-off mode and claims he works on a 200+ assembly, 3 million lines of code project every day. I'm sure he wrote that all by himself, but let's not focus on his work. The gem is in the line 'MS built the best development platform'. I'm sorry to bring it to you, Ryan, but VS.NET and the .NET framework are build with hard-core waterfall practises: cleanroom-design, hard-core specs are written out to the letter with every tiny detail explained, then the development of code is done, and after that the long process of testing and weeding out bugs starts, and after that: shipping.
Not to propagate waterfall, as for the gazillionth time: I don't like waterfall , but it's simply true. Because Microsoft uses this practise (and most other big corporates do who ship large products), it's very hard to get things changed once the hard-core spec phase is over. Most MVP's who have ever tried to give feedback to a product team, even more than a year before shipment know this the hard way: feedback is never accepted once the specs are finalized.
What Ryan apparently doesn't understand, is that I'm not anti Agile, why would I be 'anti'?. The 'Agile' movement, which first was meant to be called 'Adaptive', is actually simply a movement which pr | Go |
| Using ASP.NET AJAX with ASP.NET MVC ... Yes, you can use ASP.NET AJAX with ASP.NET MVC. Several people have asked me recently how you can use ASP.NET AJAX in an ASP.NET MVC view. In this blog entry, I’m going to explain the problem and the solution. The Problem Normally, if you want to use ASP.NET AJAX in an ASP.NET page, you add a ScriptManager control to the page. The ScriptManager control requires a server-side form control. Therefore, in order to use a ScriptManager control, you must include a server-side form control in a page. Here’s the problem. You should not include a server-side form control in an ASP.NET MVC view. Why not? Using a server-side form control violates the spirit of ASP.NET MVC since adding a form control forces you back into the Web Forms page model that forces you to use postbacks and view state. Therefore, many people have concluded, ASP.NET AJAX is not compatible with ASP.NET MVC. The Solution The solution is simple, don’t use the ScriptManager control. Instead, just include the Microsoft AJAX Library with a standard <script src=”MicrosoftAjax.js”></script> tag. You can download the standalone version of the Microsoft AJAX Library from the following location: http://www.asp.net/ajax/downloads/ The download includes multiple versions of the ASP.NET AJAX Library. The two most important scripts are named MicrosoftAjax.js and MicrosoftAjax.debug.js (the download also includes localized versions of the Microsoft AJAX Library). The MicrosoftAjax.js script is the production version of the library and the MicrosoftAjax.debug.js script is the debug version of the library. You can copy both the MicrosoftAjax.js and MicrosoftAjax.debug.js scripts directly into an ASP.NET MVC Web Application Project. A good location to add these scripts within an ASP.NET MVC application is the Content folder. After you add the scripts to your project, you can reference either the production or the debug version of the scripts within your views (or a master page). For example, the view in Listing 1 uses the Microsoft AJAX Library to wire-up a button click handler. Listing 1 – TestAjax.aspx 1: <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="TestAjax.aspx.cs" Inherits="FirstMVCApp.Views.Test.TestAjax" %>

| Windows Server 2003 - IIS6.0 Do not delete the Default Web Site! ... I being a very intelligent web developer (This is true). Decided it might be fun to delete the Default Web Site in IIS6.0 not thinking much of it. Of course it wouldn't have mattered at all, at least until I decided to install commerce server 2007 enterprise on the production server that I had deleted the Default Web Site. Why was this a problem you ask? Wow good question. Here's the long and short of it. When installing Microsoft Commerce Server 2007 sp1 you can get about oh I'd say 5 minutes into the install until you get to Web Site configuration settings. You put your user name in the little sign in box as well as your password like any good little wizard following monkey. Then terror err I mean error strikes you. The error says hey idiot I cannot find your "Default Web Site" you cannot continue. Well gall darn you say I will just right click on the web site folder and create a new web site called "Default Web Site". Ah doesn't that feel better? You say to the Monkey wizard (Commerce Server 2007 sp1 config wizard). No says the error again. So you jump up and down screaming at the server. What the brown bananas do you mean its right there! Well turns out that there is a super er... uber secret metadatabase that keeps a ID stored for every site created and the one you just created "Default Web Site" is W3SVC/890987799887.... on and on for about 6 more decimals. Problem is Windows likes the "Default Web Site" to be W3SVC/1. What do you do? Uninstall IIS? Holy foolish that would be. Try this before moving on. There is a fun little vb script built just for this occasion. "adsutil"! Remember it and love it. First we need to make sure there for whatever reason isn't a W3SVC/1 already there ( I know you are saying: but the story you took me down this long path and....) No worries its always good to dot your T's and Cross your I's or is that wrong too? Go to your nearest command prompt. make sure you are at the root of C:\ cd\Inetpub\AdminScripts once there run this: cscript adsutil.vbs enum w3svc/1 If it comes back with "path requested could not be found" you know your hosed. Try this: cscript adsutil.vbs enum w3svc All kinds of data will fly by and the world will turn upside down (unless you are in Australia. However if you are there you are smart enough not to delete the web site in the first place.). You should get: w3svc/Info w3svc/Filters and at least one w3svc/### where the number is the interesting part. To find your new default web site number will take some looking up. Hunt by using this: cscript adsutil.vbs enum w3svc/### putting the numbers you saw in the list. Ok the good part. Create the new W3SVC/1 cscript adsutil.vbs create_vserv W3SVC/1 Copy it cscript adsutil.vbs copy W3SVC/### W3SVC/1 Set It cscript adsutil.vbs set w3svc/1/ServerComment "Default Web Site" So now you have a new Default Web Site and you now know not to delete it again or there will be consequences.

| March 14th Links: ASP.NET, ASP.NET AJAX, ASP.NET MVC and .NET ... I'm slowly recovering from keynoting at MIX last week, and have been digging my way out of backlogged email the last few days. I'm going to try and finish catching up on blog comments this weekend - apologies for the delay in getting back to some of your questions. To kick-start my blogging again I thought I'd post a new link-listing series . Today's post is mostly focused on ASP.NET and web related links. I'm going to be doing more Silverlight and WPF posts soon. ASP.NET Tag Cloud Filters with ASP.NET 3.5's LinqDataSource and ListView Controls : Matt Berseth has a cool post that shows off using LINQ to SQL and ASP.NET 3.5 to build a tag-cloud navigation UI. Five New ASP.NET Security Tutorials Now Available : Scott Mitchell continues his great ASP.NET security tutorials . These 5 new ones (all in both VB and C#) cover using the ASP.NET membership system.

ASP.NET AJAX Localization Slides and Code: Joel Rumerman has a nice post with samples + slides about how the localization features in ASP.NET AJAX work. JScript Intellisense: working with Ext JS : The VS web tools team enabled JQuery intellisense last month with the VS 2008 Web Development hot fix . In this more recent post they talk about enabling intellisense support for Ext JS (another popular JavaScript framework). VS 2008 Intellisense support for Prototype is coming in the next few weeks. JavaScript Intellisense for the Virtual Earth Map Control: Marc Schweigert is driving a project to add great VS 2008 JavaScript intellisense support for the Virtual Earth Map Control. Check out his video and visit his codeplex project to learn more. ASP.NET MVC ASP.NET MVC Preview 2: Last week at MIX the ASP.NET team shipped a second preview release of the ASP.NET MVC framework. This release has a number of improvements in it (see my earlier MVC roadmap post that covers some of them). Watch the Scott Hanselman videos on the http://www.asp.net/mvc page, as well as the quickstart samples to learn more. Thoughts on ASP.NET MVC Preview 2 and Beyond : Phil Haack from the ASP.NET team has a great post where he talks about the ASP.NET MVC Preview 2 release, as well as some of the features and work that will show up in the next preview drop. One of the major focuses in Preview 3 will be improvements to the testing workflow of controllers. Cheesy Northwind Sample Code: Scott Hanselman has posted a sample application that shows building a simple data driven application using the ASP.NET MVC Framework and the Northwind sample database.

| ListViewUpdateEventArgs, Item and CheckBox Weirdness ... I went around in circles on these issues, so maybe this post will help someone else. I still haven't got a handle on what's going on. Maybe a wise and knowledgeable reader will add a comment and flesh this out. If it makes a difference, I'm using the ObjectDataSource. My goal was to get the value of a checkbox control inside a ListView <EditItemTemplate>. For some strange reason, the compiler complains about Bind() in the declarative markup for certain controls but not others. For those, the...(read more ) | Go |
| ASP.NET MVC and IE8 WebActivities ... One of the great things in readify is the ability to do Professional Development at scheduled intervals to keep up to speed with the latest industry technologies and advancements. My latest foray into this (amongst other things) has been looking at the ASP.NET MVC framework and Internet Explorer 8 WebActivities . Both of these technologies are quite cool and I wanted a way to learn about them both and link them in some way where I could learn about them at the same time. To that end, I created a solution in Visual Studio 2008 which utilises the ASP.NET MVC framework and allows a user to enter some fields to create an IE8 Web Activity definition. You can then view the XML definition, and click the 'Add' button to add that activity to Internet Explorer 8 as a proper web activity. The web activity generated is not particularly functional, but does allow previews, icon definition, execute actions, however has no current support for parameters. Again, not really intended as a fully fledged utility or application, but a good way to learn about both the MVC framework and IE8 activities. The solution can be downloaded here . Obviously, you need Visual Studio 2008, the ASP.NET MVC preview 2 framework , and have Internet Explorer 8 beta installed. Feel free to download, play, chop up etc... | Go |
| VSLive San Francisco in Less Than 3 weeks ... Yes, it is that time of year again (and I say that most happily!) to go out to San Francisco to speak at the VSLive Conference. This year I am focussing on real-world use of DataSets, both with VS 2005 and VS 2008. But don't attend just for that - there are many other great sessions and speakers that you will really enjoy and learn from.
In order to make it easier (i.e cheaper) for you to attend, you can receive a $695 discount on the Gold Passport if you register using priority code SPGOL . More at www.vslive.com/sf - be sure to ping me if you are going to be there!
Here are the descriptions for the sessions I am doing:
Using and Extending the Typed DataSet and TableAdapter Are you using the VS 2005 DataSet designer to design your data access code usign Typed DataSets and Table Adapters? You should be - because doing so allows you to build better data access code much faster. This session will be mainly demos that cover both the basic uses of these tools and objects, as well as techniques to extend the standard classes to meet your own specific needs. We will also take a look at some of the improvements in Visual Studio 2008.VS Tools and Techniques for Distributed Data Access in VS 2008 This session will discuss several challenges facing developers developing distributed data access applications. These issues include hierarchical updates, use of VS tools/wizards to generate truly N-tier applications, and separation of data entity and data access objects. We will demonstrate what tools and techniques can be used and take a look at what new solutions are offered in Visual Studio 2008. | Go |
| Italian Configuration File for GhostDoc 2.1.3 ... Even though GhostDoc is intended for English documentation (and there are no plans for future versions to change that), Luca Tagliaferri from Italy has created an Italian configuration file for GhostDoc 2.1.3. While I cannot comment on the quality (I haven't tried it, non parlo l'italiano), I recommend checking it out here . Just be sure to export your current configuration as a backup. | Go |
