| ASP.NET Dynamic Data Preview Available ... A few months ago we released an ASP.NET 3.5 Extensions Preview that contained a bunch of new features that will be shipping later this year (including ASP.NET AJAX Improvements, ASP.NET MVC, ASP.NET Silverlight Support, and ASP.NET Dynamic Data). The ASP.NET Dynamic Data support within that preview provided a first look at a cool new feature that enables you to quickly build data driven web-sites that work against a LINQ to SQL or LINQ to Entities object model. ASP.NET Dynamic Data allows you to automatically render fully functional data entry and reporting pages that are dynamically constructed from your ORM data model meta-data. In addition to supporting a dynamic rendering mode, it also allows you to optionally override and customize any of the view templates using any HTML or code you want (given you full control of the experience). ASP.NET Dynamic Data Preview Today we released an updated ASP.NET Dynamic Data Preview. You can learn more about it and download it here . This new dynamic data preview now works with the standard built-in ASP.NET data controls (GridView, ListView, FormView, DetailsView, etc). The dynamic data support enables these controls to automatically handle foreign-key relationships. For example, on a gridview you'll now get automatic friendly name display of foreign key column values and automatic drop-down list selection support of these values when in edit mode: The new dynamic data support also provides automatic UI validation support (both client-side and server-side) based on the constraints you set on your data model classes. For example, if a column in the database is limited to 50 characters in size, and is marked as non-nullable, appropriate UI control validators will automatically be applied by ASP.NET dynamic data to enforce this constraint in the UI pages as well. If you change the constraints within your LINQ to SQL or LINQ to Entities data model classes, the UI will automatically pick up these changes and enforce the new constraints on the next web request. In addition to standard data model metadata, you can also declare custom metadata to further control validation and the default display of UI of objects. You will be able to use all of the above features with both LINQ to SQL and LINQ to Entities. Visual Studio Dynamic Data Project Wizard In addition to the core ASP.NET dynamic data runtime support, the VS web tools team today also shipped a first preview of a new dynamic data project wizard that enables you to quickly get a data driven web-site started. The wizard allows you to select a database, and then the tables, views and sprocs within it that you want to build a LINQ to SQL data model around: After creating a data model, the wizard allows you to easily choose dynamic data driven template pages to build UI around it: You can then choose what type of inserting/editing/updating UI is supported on each page: And when you click finish it will setup a project with your data model classes and data UI pages setup to run. You can learn more about the wizard and watch it in action in a blog post and screencast here . How to Get Started You can learn more about this new dynamic data preview and download and run it locally here . You can watch David Ebbo's dynamic data presentation at MIX 08 to learn more about how it works. Also check out Scott Hunter's screen-cast here , and Brad Millington's screen cast here . David also has a post here that talks about the changes made between the December preview and today's preview release. You can ask questions and submit feedback via the www.asp.net forums here . Hope this helps, Scott | 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 |

| 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 |

However, at times you need to retrieve schema information from the database. Suppose you are building applications that performs data import and export between two or more databases. 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 |

| ASP.NET Dynamic Data Preview Available ... A few months ago we released an ASP.NET 3.5 Extensions Preview that contained a bunch of new features that will be shipping later this year (including ASP.NET AJAX Improvements, ASP.NET MVC, ASP.NET Silverlight Support, and ASP.NET Dynamic Data). The ASP.NET Dynamic Data support within that preview provided a first look at a cool new feature that enables you to quickly build data driven web-sites that work against a LINQ to SQL or LINQ to Entities object model. ASP.NET Dynamic Data allows you to automatically render fully functional data entry and reporting pages that are dynamically constructed from your ORM data model meta-data. In addition to supporting a dynamic rendering mode, it also allows you to optionally override and customize any of the view templates using any HTML or code you want (given you full control of the experience). ASP.NET Dynamic Data Preview Today we released an updated ASP.NET Dynamic Data Preview. You can learn more about it and download it here . This new dynamic data preview now works with the standard built-in ASP.NET data controls (GridView, ListView, FormView, DetailsView, etc). The dynamic data support enables these controls to automatically handle foreign-key relationships. For example, on a gridview you'll now get automatic friendly name display of foreign key column values and automatic drop-down list selection support of these values when in edit mode: The new dynamic data support also provides automatic UI validation support (both client-side and server-side) based on the constraints you set on your data model classes. For example, if a column in the database is limited to 50 characters in size, and is marked as non-nullable, appropriate UI control validators will automatically be applied by ASP.NET dynamic data to enforce this constraint in the UI pages as well. If you change the constraints within your LINQ to SQL or LINQ to Entities data model classes, the UI will automatically pick up these changes and enforce the new constraints on the next web request. In addition to standard data model metadata, you can also declare custom metadata to further control validation and the default display of UI of objects. You will be able to use all of the above features with both LINQ to SQL and LINQ to Entities. Visual Studio Dynamic Data Project Wizard In addition to the core ASP.NET dynamic data runtime support, the VS web tools team today also shipped a first preview of a new dynamic data project wizard that enables you to quickly get a data driven web-site started. The wizard allows you to select a database, and then the tables, views and sprocs within it that you want to build a LINQ to SQL data model around: After creating a data model, the wizard allows you to easily choose dynamic data driven template pages to build UI around it: You can then choose what type of inserting/editing/updating UI is supported on each page: And when you click finish it will setup a project with your data model classes and data UI pages setup to run. You can learn more about the wizard and watch it in action in a blog post and screencast here . How to Get Started You can learn more about this new dynamic data preview and download and run it locally here . You can watch David Ebbo's dynamic data presentation at MIX 08 to learn more about how it works. Also check out Scott Hunter's screen-cast here , and Brad Millington's screen cast here . David also has a post here that talks about the changes made between the December preview and today's preview release. You can ask questions and submit feedback via the www.asp.net forums here . Hope this helps, Scott | Go |

| Silverlight 2 Networking Options ... I've been spending my nights working on a new book covering Silverlight 2 and have been focusing on the new networking features that are available in the System.Net and related namespaces. Silverlight's great at animating objects, performing transformations and collecting data with all of the new controls that are available, but at some point you'll need to retrieve data or send data to a service. There's great support built-in for calling WCF services, ASMX services as well as other services. Support for calling REST APIs is also very good and easy to implement using classes such as WebClient and HttpWebRequest/HttpWebResponse. Asynchronous requests can be issued and handled quite easily once you figure out the pattern (which is quite consistent throughout the different networking classes). Serialization and Deserialization Options Once data returns from a service you can parse it using multiple techniques. I'll blog about these individually over the next few months but in a nutshell you can map XML data into CLR objects in Silverlight 2 using the XmlReader class, XmlSerializer class or the LINQ to XML technology and related classes such as XDocument. JSON can be mapped to CLR objects using the DataContractJsonSerializer and other open source options are available at http://www.codeplex.com . RSS and ATOM feeds can be parsed and items/entries can be accessed using classes such as SyndicationFeed and SyndicationItem. All of this functionality is straightforward to use especially if you have a background in VB.NET or C#. The available networking and parsing classes make working with data (especially XML data) a pleasant experience. Support for Sockets In addition to the request/response features built into Silverlight 2 you can also use sockets to communicate and exchange data. A socket is basically a port and an IP address used to send data between a client and a server. Currently Silverlight 2 supports port ranges between 4502 and 4532 although it's possible that may change since it's still in the beta 1 stage. By using sockets a Silverlight client can talk directly with a server that listens for client connections and the server can push data to the client without requiring the client to consistently poll the server for changes...that's cool! If you've seen some of the sports scoring applications at ESPN.com then you've experienced some of the push technologies that are out there. I wanted to play around with the new sockets capabilities so I decided to build a sample application that could push simulated basketball game scores down to a client. Multiple clients can connect to a socket server and the server can then push the same data out to the clients which is kind of interesting since they stay in sync. I'm not going to go into details on the implementation of the server or Silverlight client in this post (those attending DevConnections Orlando will get some of this in my Silverlight 2 talk), but I'll be breaking down the different pieces in posts coming in the near future. Until then, here's what the application looks like at this point. Score data is sent as XML from the server to the client along with details about what action occurred in the game. The game data is randomly generated on the server to simulate turnovers, fouls, 2 point shots, 3 point shots and foul shots. There's a lot more than can be done to enhance the application, but here's what it looks like to this point. I'll be posting details about how to build a server and client that communicate via sockets soon. In the meantime make sure you check out Tim Heuer's blog on Silverlight 2 topics. He's a Silverlight Evangelist for Microsoft (and good buddy) and has some awesome posts on Silverlight. He posts about things that I haven't seen anywhere else.

| Active Control Marker ... Today, while working on my project, I recalled that some of the data entry pages in my project have a lot of textboxes, which may confuse the end-user once he starts entering information. My idea was to make the textbox that has focus visually different from the rest, so I came up with the following code snippet, that does the actual work: Public Sub ShowActiveTextbox(ByVal txt as TextBox) txt.Attributes.Add("onfocus", "this.className='myStyle1'") txt.Attributes.Add("onblur", "this.className='myStyle2'") End Sub This code would work just fine if I had only one or two Textboxes on my page. However, some of the pages may contain a dozen of those textboxes, so I came up with another useful method: Public Sub ShowActiveTextbox(ByVal col As ControlCollection) For Each Ctl as Control in col If Ctl.GetType().Name = "Textbox" Call ShowActiveTextbox(Ctl) End If Next End Sub | Go |

| Unit Test Projects or Not? ... It's funny how the world works. A butterfly flaps it's wings in Brazil, and a tornado forms in Texas 1,000 miles away. Phil Haack posted a poll about unit test project structure and asked the very question we've come to on our current project. Should unit tests belong in their own project or as part of the system? I was going to post a comment on Phil's entry, but figured I would drag my explanation and description out to a full post here. In the past I've *always* created a separate test project. Tree Surgeon by default does this (and now I'm looking at adding an option to let you decide at code generation time) and most projects I know of work this way. You create your MyApp.Core project (containing your domain logic) and a MyApp.Test project with all the unit tests. More recently I've been creating MyApp.Specs project but that's just a different evolution. In the next project we're working on, we're looking to shift this approach. A shift to include unit tests in our MyApp.Core project. Here's some reasons and thinking behind it. With unit tests (or specifications) in a separate project you end up mimicking the structure of your domain and create a namespace hierarchy. By default .NET assemblies have a default namespace for your application and then the name of any folder in the project is appended to the default namespace. So if your assemblies default namespace is MyApp.Core (and the namespace defaults to the name of the assembly) and you create a folder called Customer, all classes in that folder will be in the MyApp.Core.Customer namespace. In your test project you have a similar thing and usually you'll have the default namespace to be MyApp.Test (the name of the assembly). Since there is only one test assembly (assuming you don't break them up that is) then you don't necessarily want to create a folder called CustomerSpecs (or CustomerTests or even Customer) so you might create a folder called Domain. After all, you're unit testing the domain but then they'll be the UI, Presenters, Factories, Data Access, etc. Do you create a separate test assembly for all of these? Probably not. Let's see, we have an assembly (MyApp.Core), a class (Customer) in a namespace (MyApp.Core.Customer). Now you've got a test assembly (MyApp.Test), a set of Customer tests (CustomerSpecs.cs or CustomerTests.cs or whatever) in a domain namespace (MyApp.Test.Domain). This is getting a little complicated, but no big deal from a resolution perspective. You'll just bring in the namespaces you need and bang (or BAM!). However two things seem to arise out of this setup. First (which might kick off it's own huge debate) you need access to your Customer class and potentially other classes, enumerations, etc. that it uses which are locked away in MyApp.Core.dll. That means you have two options. Either you make the Customer class public or you use the InternalsVisibleTo attribute to let MyApp.Test.dll see the stuff inside of MyApp.Core.dll. There's another option here, slam all the files into one assembly and don't worry about it from a testing perspective. That might alleviate the problem but that's a different blog entry. The second thing that comes out of this is a fairly deep and wide namespace hierarchy in your test assembly. That might not be a big deal unto itself, but could be an inconvenience. In addition the deep impact this might cause, let's say you have 30 domain classes and the subsequent 30 or so fixtures (or more, or less, doesn't really matter). And these are scattered around in various folders. Each time you touch the fixture to write a test or look at the domain object and create some test, you're playing hunt and peck inside your test assembly to find the right spot to match the folder structure. Of course if you don't care and toss everything into a single folder you won't care, but I think that's a different type of maintenance you don't want to get into. Then, let's say you restructure your domain (which can happen a few times thro | Go |
