Over the years, there have been various solutions that circumvent the stateless limitation of Web applications, with the focus on reducing the number of page calls or reloads to avoid hampering the user experience. For example, many developers used hidden frames to serve as data sources so data could easily be sent to or retrieved from the hidden frame page. Also, some developers chose to load everything with the initial load, so subsequent page loads are reduced. | Go |

| Tip/Trick: Creating and Using Silverlight and WPF User Controls ... One of the fundamental design goals of Silverlight and WPF is to enable developers to be able to easily encapsulate UI functionality into re-usable controls. You can implement new custom controls by deriving a class from one of the existing Control classes (either a Control base class or from a control like TextBox, Button, etc). Alternatively you can create re-usable User Controls - which make it easy to use a XAML markup file to compose a control's UI (and which makes them super easy to build). In Part 6 of my Digg.com tutorial blog series I showed how to create a new user control using VS 2008's "Add New Item" project item dialog and by then defining UI within it. This approach works great when you know up front that you want to encapsulate UI in a user control. You can also use the same technique with Expression Blend. Taking Existing UI and Encapsulating it as a User Control Sometimes you don't always know you want to encapsulate some UI functionality as a re-usable user control until after you've already started defining it on a parent page or control. For example, we might be working on a form where we want to enable a user to enter shipping and billing information. We might begin by creating some UI to encapsulate the address information. To-do this we could add a <border> control to the page, nest a grid layout panel inside it (with 2 columns and 4 rows), and then place labels and textbox controls within it: After carefully laying it all out, we might realize "hey - we are going to use the exact same UI for the billing address as well, maybe we should create a re-usable address user control so that we can avoid repeating ourselves". We could use the "add new item" project template approach to create a blank new user control and then copy/paste the above UI contents into it. An even faster trick that we can use within Blend, though, is to just select the controls we want to encapsulate as a user control in the designer, and then "right click" and choose the "Make Control" menu option: When we select the "Make Control" menu item, Blend will prompt us for the name of a new user control to create: We'll name it "AddressUserControl" and hit ok. This will cause Blend to create a new user control that contains the content we selected: When we do a re-build of the project and go back to the original page, we'll see the same UI as before - except that the address UI is now encapsulated inside the AddressUserControl: We could name this first AddressUserControl "ShippingAddress" and then add a second instance of the user control to the page to record the billing address (we'll name this second control instance "BillingAddress"): And now if we want to change the look of our addresses, we can do it in a single place and have it apply for both the shipping and billing information. Data Binding Address Objects to our AddressUserControl Now that we have some user controls that encapsulate our Address UI, let's create an Address data model class that we can use to bind them against. We'll define the class like below (taking advantage of the new automatic properties language feature): Within the code-behind file of our Page.xaml file we can then instantiate two instances of our Address object - one for the shipping address and one for the billing address (for the purposes of this sample we'll populate them with dummy data). We'll then programmatically bind the Address objects to our AddressUserControls on the page. We'll do that by setting the "DataContext" property on each user control to the appropriate shipping or billing address data model instance: Our last step will be to declaratively add {Binding} statements within our AddressUserControl.xaml file that will setup two-way databinding relationships between the "Text" properties of the TextBox controls within the user control and the properties on the Address data model object that we attached to the user control: W | Go |
| Unit Testing with Silverlight ... One of the important capabilities we shipped with the Beta1 release of Silverlight 2 was a unit test harness that enables you to perform both API-level and UI-level unit testing. This testing harness is cross browser and cross platform, and can be used to quickly run and verify automated unit tests: In addition to shipping this unit test harness for Silverlight, we also shipped the source to ~2,000 unit tests built with it that provide automated coverage for the Silverlight control source that we also shipped under a permissive license (you can take the control source, modify it, run the unit tests to verify the behavior, then re-ship the controls however you want). Learning How to Unit Test Silverlight Jeff Wilcox (who developed the Silverlight unit test framework and harness) has a great blog post that talks about how to add a Silverlight Unit Test project to a solution here . You can download the chat application that he shows testing from this expression blend blog post tutorial I did last month. You can also watch this cool video post that Jeff created where he walks through the unit test framework and test cases we've shipped. As Jeff shows in his post, you can now add a "Silverlight Test Project" to your Visual Studio solution which encapsulates unit tests for an application you are working on: You can then add unit test classes to the test project that test APIs or simulate UI action within the Silverlight controls (simulate button clicks, etc). You can then run the test project and execute the tests within it to verify and report their status. Jeff's test framework automatically provides a browser based test harness and reporting system (which means you can run it on any browser/OS combination that Silverlight runs on): Jeff's test framework supports quickly re-setting controls after each test (and avoids needing to re-launch a new browser instance for each test cases - which makes it really fast). You can quickly rip through hundreds or thousands of automated tests in seconds: Green results mean the tests passed. Red results flag that a test case failed and log the assertion failure and/or runtime exceptions that occurred. Summary If you've ever struggled to try and come up with a strategy for doing automated unit testing or TDD with AJAX applications, I think you'll find Silverlight provides some much nicer test options. Using Visual Studio you can also separate your tests into a separate project in your solution, and you do not need to embed the tests within your Silverlight application in order for them to run. In addition to supporting the above unit test harness and framework, we are also going to support UI automation APIs with the final release of Silverlight 2. These will enable accessibility scenarios (allowing screen readers to work with Silverlight and enable Section 508 compliance of Silverlight applications). These UI automation APIs will also enable UI testing scenarios where you can build end to end browser UI automation that simulates real mouse and keyboard interactions and enables automated end to end experience testing. The combination should enable you to build much more solid and maintainable RIA solutions. Hope this helps, Scott P.S.

| New Log Reporting, Database Management, and other cool admin modules for IIS 7 ... One of the core priorities we focused on when building IIS 7 was to enable a rich .NET extensibility model that provides developers with the hooks to easily plug-in and extend the web server. These extensibility hooks are provided in the web-server pipeline (enabling scenarios like the new IIS7 Bit Rate Throttler ), within the configuration system (enabling developers to create new web.config schema settings), within the health monitoring system (enabling developers to add custom trace events), and within the admin tool (enabling developers to plug-in new admin UI modules). We added these extensibility hooks so that anyone can easily extend and enhance the web server using .NET. We also selfishly wanted them so that we can ship regular feature packs that add additional features to the core web server. IIS 7 Admin Pack Preview 1 Released Last week the IIS team shipped the first technical preview of some really cool administration modules that I think web developers will find super useful. This preview adds several new features to the IIS7 Admin Tool: Database Manager : Built-in SQL Server database management, including the ability to create, delete, and edit tables and indexes, create/edit SPROCs and execute custom queries. Because it is integrated in the IIS administration tool it all works over HTTP/SSL - which means you can use the module to remotely manage your hosted applications (even with low-cost shared hosting accounts), without having to expose your database directly on the Internet. Log Reports : Built-in report visualization with charting support for log files data. Full range selection and custom chart creation is supported, as well as the ability to print or save reports. Like the database manager you can use this module remotely over HTTP/SSL - which means it works in remote shared hosting scenarios. Configuration Editor: This is a power module that provides complete control over editing all web.config settings within the admin tool. You can configure it to track the changes you make using the UI and have it auto-generate configuration change scripts that you can then save and tweak to re-run later in an automated way. Request Filtering UI: This admin module provides more control over the new request filtering feature in IIS7. Check out Carlos' blog post here for details on how to use it. .NET Authorization: This admin module provides a custom authorization rules editor which allows you to more easily manage the ASP.NET <authorization> configuration section. FastCGI UI: This admin module provides more support for editing all the new <fastCGI> settings (for when you use FastCGI modules with IIS7 like PHP). Below are some screen-shots and simple walkthroughs of the Log Reporting and Database Manager administration UI modules: Log Reporting Admin Module Have you ever deployed a web application onto a server and wondered how much load it is getting?, what the average response time from the server is?, or whether many server errors are occurring (and if so on what URLs)? All of these settings are carefully logged by IIS in a text based log file. Today most people use command-line tools like the IIS Log Parser utility to query and analyze these files. The IIS 7 Admin Pack and the new "IIS Reports" admin module now enable you to also query and chart your reports graphically within the IIS admin tool: Out of the box the "IIS Reports" admin module comes with a bunch of pre-built logparser-based reports that you can easily run on your sites and applications: Below is a simple graphical report we could pull up that looks at the HTTP status codes being returned by my "TestSite" application (note how we are using the "bar graph" visualization option): Reports can optionally be filtered using a date range. You can also push the print or save buttons within the report page to generate a printer or a local saved version of the report. The IIS7 Admin To | Go |
| ASP.NET MVC Source Code Now Available ... Last month I blogged about our ASP.NET MVC Roadmap . Two weeks ago we shipped the ASP.NET Preview 2 Release . Phil Haack from the ASP.NET team published a good blog post about the release here . Scott Hanselman has created a bunch of great ASP.NET MVC tutorial videos that you can watch to learn more about it here .
One of the things I mentioned in my MVC roadmap post was that we would be publishing the source code for the ASP.NET MVC Framework, and enable it to be easily built, debugged, and patched (so that you can work around any bugs you encounter without having to wait for the next preview refresh release).
Today we opened up a new ASP.NET CodePlex project that we'll be using to share buildable source for multiple upcoming ASP.NET releases. You can now directly download buildable source and project files for the ASP.NET MVC Preview 2 release here .
Building the ASP.NET MVC Framework
You can download a .zip file containing the source code for the ASP.NET MVC Framework for the release page here . When you extract the .zip file you can drill into its "MVC" sub-folder to find a VS 2008 solution file for the project:
Double-clicking it will open the MVC project containing the MVC source within VS 2008:
When you do a build it will compile the project and output a System.Web.Mvc.dll assembly under a \bin directory at the top of the .zip directory. You can then copy this assembly into a project or application and use it.
Note: the license doesn't enable you to redistribute your custom binary version of ASP.NET MVC (we want to avoid having multiple incompatible ASP.NET MVC versions floating around and colliding with each other). But it does enable you to make fixes to the code, rebuild it, and avoid getting blocked by an interim bug you can't work around.
Next Steps
Our plans are to release regular drops of the source code going forward. We'll release source updates every time we do official preview drops. We will also release interim source refreshes in between the preview drops if you want to be able to track and build the source more frequently.
We are also hoping to ship our unit test suite for ASP.NET MVC in the future as well (right now we use an internal mocking framework within our tests, and we are still doing some work to refactor this dependency before shipping them as well).
Hope this helps,
Scott | Go |
| IIS 7.0 Bit Rate Throttling Module Released ... Video on the web is now one of those common scenarios that every user takes for granted, and increasingly every major site is incorporating in some form (product videos, training videos, richer advertising scenarios, user generated content, customer testimonials, etc).
One of the challenges when adding video to a site, though, is delivering it in a way that doesn't cost a fortune. Network bandwidth costs a lot of money, and the cost of high quality video usage can quickly add up.
The blog post below provides a quick overview of some of the options you can use to reduce the cost of delivering video, and discusses a new free download - the IIS 7.0 Bit Rate Throttling Module - that was released a few days ago and which enables you to easily save money when serving video from an IIS web server using any video technology (including Silverlight, Windows Media Player and even Flash).
Option 1: Using a Video Hosting Service
One approach you can take to reduce video bandwidth costs is to use a video hosting service like YouTube or the free Microsoft Silverlight Streaming Service . This allows you to use someone else's network to deliver the video content, and avoid having to pay the bandwidth costs yourself.
If you aren't familiar with the Silverlight Streaming service, it allows you to upload up to 10GB of videos and download 5 Terabytes/month of video content (at up to a 1.4 Mbps bit-rate) for free. You can build any custom Silverlight client player application you want to embed the video within it. This means it doesn't require a specific video player look and feel, nor a service logo/watermark to play the video. This allows you to fully integrate the video into your site and use whatever UI you want to host it.
Option 2: Hosting Video on Your Own Servers
Sometimes using a video hosting service doesn't make sense (for example: you want to use custom authentication to grant/deny user's access, you want to play really long video segments, or you want to serve up custom ads in your videos). Instead you might want to serve the video up from your own servers and have complete control over it.
There are typically two options you can use to deliver the video from your servers: using a streaming approach or a progressive video download approach:
Streaming Server Scenario
In a streaming scenario a client (like Silverlight, Windows Media Player, Flash or Real Networks) connects to a streaming server. The streaming server then sends down the video stream to watch, and typically enables a user to dynamically skip ahead/behind, pause or stop the video stream. When the user closes the browser or navigates away from the page the video stream automatically stops transmitting.
Windows Media Services (WMS) is a free streaming server download available for Windows, and can stream video to both Windows Media Player and cross-platform Silverlight browser clients. It is generally regarded as the most server scalable and cost effective way to enable video streaming on the web, and handles both on-demand file streaming scenarios (for example: streaming a .wmv file) as well as live stream scenarios (for example: a sporting event like the Olympics that is happening live in real time).
Windows Media Services can be used on any version of Windows Server - including the new Windows Server 2008 Web Server edition (which only costs $469, enables up to 4 processors and 32GB of RAM, and supports IIS, ASP.NET, SharePoint, and Windows Media Services).
Progressive Download Scenario
In a progressive download scenario a client (like Flash or Silverlight) downloads a video directly off of a web-server, and begins playing it once enough video is downloaded for it to play smoothly.
The benefit of using a progressive download approach is that it is super easy to setup on a web-server. Just copy/ftp a video up to a web-server, obtain a URL to it, and you can wire it up to a video client player. It doesn't require any custom web-server configurat | Go |

| 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.
<Download Code> Click here to download a completed version of this sample. </Download Code>
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:

| 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.

| 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 |

| Getting Started with the ASP.NET MVC Framework ... We have made a long journey from classic ASP to ASP.NET. But the journey is far from over. ASP.NET framework introduced code behind model which eliminated the spaghetti code written in classic ASP. Although the code behind model made the life of an ASP.NET developer comfortable but it was far from being perfect. The biggest drawback was not able to test the code written in the code behind. The model was also dependent on the ViewState and Postback which introduced many other issues related to web programming. Recently, Microsoft released the CTP version of the ASP.NET MVC framework that solves some of these issues. In this article we are going to take a look at the different aspects of the MVC framework by creating a small application. | Go |

As a good solution you would want to retrieve table schema at runtime rather than hard coding it. Luckily, ADO.NET provides a set of classes that allow you to query database schema. In this article I will illustrate how these classes work. | Go |

| Visual Studio 2008 (Beta 2) Install - Easter Egg? ... Exactly one week ago, I was testing something that required me to install the old Visual Studio 2008 (Beta 2) on a virtual machine. I got part way through the install when a bizarre set of circumstances led to my accidentally sitting on the keyboard. A bunch of buttons got pressed in some random order, and all of a sudden the screen switched to this: After a few seconds, it went back to the normal install screens with Mr. Tiny Face . I was able to grab a screenshot of the first screen with TimeSnapper , but for the life of me I can't figure out what the keystroke combination was that made it show. I've tried sitting on my keyboard, bashing random keys, and even looking at the executable resources. After a week of trying, I'm giving up - I just can't get it to show up again. Maybe it was keyed to the date, somehow? I'm glad I've at least got that screenshot, or no one would believe this. You believe me, don't you? | Go |

| Conventions and Practices to keep in mind ... The last week I was preparing for a training session about programming conventions and practices to adapt some new developers who will join my team. While I am trying to acquire a good material of my presentation I thought: there is no way to find a good material than going to the source Microsoft use in some of their products. Here comes our man Juval Löwy. I took it's great book "Programming .NET Components" which conations nice appendix called "C# coding standers". In this part of his book he presented a summarized main standards of coding with out entering in every detail and make the reader confused. Coding standers is one of things every developer must keep in his mind before starting writing suck code here and their and setup a hell for the person who will try to update or make some maintenance in this f*** code. I run in a such thing, I was involved in one of our company mature projects which supposed to be written by senior developers. The tough truth that I burned in their coding hell. Some methods with more than 500 lines of codes, hundreds of naming styles is used, thousands of uncommented methods and then you stop and stare what this piece of sh** is doing. Without forcing developers to follow the same coding standard you will face this problem in every project event it's a simple one which contains some classes only. Every one should do coding the same way others in the team do, in spite of he some times may does not know why he should. As Juval Löwy said : "Being able to comply with a good standard should come before fully understanding and appreciating it, that should come over time, with experience. " As I said first I took this part of book and make some presentation slides and categorized them in groups.Their is another tow section about "Project Setting and Project Structure", and "Framework Specific Guide-Line " I don't include in those slides. I hope those help to keep standers in your mind while you doing your daily development work. And keeping you committed with best practices and conventions. Happy programming You can get those slides from attachments below | Go |
| Teste de Unidade com Silverlight ... Uma das funcionalidades apresentadas na versão Beta1 do Silverlight 2 é um framework de automação de testes que possibilita a execução de testes de unidade tanto a nível da API como em interfaces para o usuário. Junto ao lançamento deste framework de automação, foram também disponibilizados aproximadamente 2.000 testes de unidade realizados que permitem a cobertura automatizada do código fonte para o Silverlight , que também foi disponibilizado sob uma licença de permissão (você pode ter o código fonte, modificá-lo, executar os testes unitários e verificar o comportamento para então disponibilizar os controles novamente como desejar). Como Realizar Testes Unitários no Silverlight Jeff Wilcox (que desenvolveu o framework de testes unitários e a automação destes testes para Silverlight) tem um ótimo post em seu blog onde é apresentado como adicionar um projeto de Teste Unitário para Silverlight a uma solução. Você pode fazer o download da aplicação de chat utilizada para testes neste post do Expression Blend feito no último mês. Você pode ainda assistir a este vídeo post que Jeff criou onde é realizado um passo-a-passo através do framework de testes unitários e dos casos de testes que foram disponibilizados. Assim como Jeff apresenta em seu blog, agora você pode adicionar um "Silverlight Test Project" para a sua solução no Visual Studio que encapsula testes unitáros para uma aplicação em que você esteja trabalhando: Você pode então adicionar classes para testes unitários ao projeto e assim testar APIs ou simular ações de interfaces do usuário com controles Silverlight (simular clicks em botões etc). Você pode então executar o projeto teste e realizar os testes inclusos nele para verificar os status dos mesmos. O framework de testes criado por Jeff oferece ferramentas e relatórios via browser (o que significa que você pode acessá-los de qualquer combinação de navegador / sistema operacional com suporte ao Silverlight): O framework suporta a re-definição simplificada de controles depois de cada teste (evitando a necessidade de uma nova instância do browser para cada caso de teste - o que torna a ferramenta realmente rápida). Você pode rapidamente percorrer centenas de milhares de testes automatizados em segundos: A sinalização verde representa que os testes obtiveram sucesso. Sinais vermelhos indicam que o caso de teste falhou e são registradas as falhas e/ou exceções em tempo de execução que ocorreram. Resumo Se você já lutou tentando alcançar uma estratégia para a realização de testes unitários automatizados ou TDD em aplicações AJAX, acredito que você irá descobrir que o Silverlight oferece algumas boas opções de teste. Utilizando o Visual Studio você pode ainda separar os testes em um projeto da sua solução, e não precisará agregar os testes com a aplicação Silverlight no momento da execução da aplicação. Além de oferecer suporte ao framework de testes apresentado, vamos também oferecer suporte para automação de APIs de interfaces do usuário com a versão final do Silverlight 2. Isto irá habilitar cenários de acessibilidade (permitindo leitores de telas a trabalhar com o Silverlight e habilitar compatilidade entre as regras do projeto Section 508 e aplicações Silverlight). A automação destas APIs de interfaces com o usuário irá possibilitar também cenários de testes onde você poderá criar automação para estas interfaces incluindo interação real de mouse e teclado além de habilitar testes de experiência. Esta combinação irá possibilitar a criação de soluções RIA mais consistentes e com melhor manutenibilidade. Espero ter ajudado, Scott (Tradução por João Almeida) P.S.

| CPU Scheduling Simulator 1.0 released! ... I've said it all before in recent posts, but here it is again - CPUSS is a framework that allows you to design and analyse CPU scheduling algorithms. Download CPUSS 1.0 There is a tonne of stuff in CPUSS! Most of which is not exposed by the report generation tool (CPUSSRG). Using the CPUSS API you can look at very atomic stats of each and every process that was in the simulation, events for process start, completion, preemption, and resuming. Download CPUSS 1.0 You can use CPUSS to analyse your won custom algorithms very easily, go to the download page of CPUSS 1.0 and grab the PDF file that explains how to do it, and the API document is quite comprehensive. Download CPUSS 1.0 If you are interested in scheduling algorithm (strategy) design and analysis then give it a go! This will be the only release of CPUSS, I may update it a little if there are any major bugs found but it started off as a research project so it won't go any further - it has proved what it needed to prove. Download CPUSS 1.0 Seriously go check it out if you are into this stuff. Oh, and finally a BIG thank you to everyone who downloaded the releases and played with them! Thank you! | Go |
| Hello Blog World ... Welcome to my personal blog. I'm sure you have questions such as who am I, what do I do, and what is this blog all about.
I'm Jon Cortez and I been living in the Seattle area for the past 12 years. I work in Bellevue for Statera (a consulting company headquartered in Denver) as a Senior SharePoint Architect. I'm in charge of building our SharePoint consulting practice here in Seattle. On this blog, I'll be posting things related to MOSS 2007 and other Microsoft technologies that I believe would be of value to other technologists out there. As a consutant, each day is a day of problem solving for me. And my goal is to share those experiences (i.e. the joys and frustrations) working with technology.
