Jared Bienz has been working on getting some cool WPF transitions code posted to codeplex. The project, Transitionals , is now live! Transitionals is a framework for building and using WPF transitions which provide an easy way to switch between UI views in a rich and animated way. Think of transitions for applications in the same way you think of transitions for video editing. Wipe , Cut , Dissolve , Star, Blinds and 3D Rotating Cube are all examples of transitions supported by the Transitionals framework. The best way to get started with the Transitionals framework is to download and take a look at the TransitionalsHelp file. You can find it on the Releases tab and it includes a pretty comprehensive Getting Started guide. You can also...
Here is the latest in my link-listing series . Also check out my ASP.NET Tips, Tricks and Tutorials page and Silverlight Tutorials page for links to popular articles I've done myself in the past.

In this article he discusses how to use ASP.NET's Membership features to estimate and display the number of active users currently visiting a site. ASP.NET Dynamic Data Update : The ASP.NET team last week released an update of the new ASP.NET Dynamic Data feature. This update adds several new features including cleaner URL support using the same URL routing...
Krzysztof recently announced on his blog that we have begun working on an extensibility framework for .NET.. We will blog more details about MEF in the upcoming months, but here are some early details (subject to changes, of course): MEF is a set of features referred in the academic community and in the industry as a Naming and Activation Service (returns an object given a “name”), Dependency Injection (DI) framework, and a Structural Type System (duck typing). These technologies (and other like System.AddIn) together are intended to enable the world of what we call Open and Dynamic Applications, i.e. make it easier and cheaper to build extensible applications and extensions. [....] And finally here is some code showing basic...
Last week I presented at the ASP.NET Connections Conference in Orlando. I gave a general session talk on Monday, and then two breakout talks later that day. You can download my slides+samples below: General Session The slides for my keynote can be downloaded here . In the talk I demonstrated how to debug the .NET Framework source code. You can learn how to set this up with VS 2008 here . I also demonstrated building a site using the new ASP.NET Dynamic Data support - which you can learn more about here . I also demonstrated using the new ASP.NET MVC Framework - which you can learn more about here . I also showed off the new Hard Rock Memorabilia site built with Silverlight 2. You can try out the Hard...
I've noticed quite a few people run into the issue "Why is design mode empty for my web user control (ASCX)?". It's not obvious what might be causing this bug, so I thought I'd offer an explanation and a couple workarounds. Problem You have a user control that has a "link" tag to an external style sheet or a "style" tag with local styles at the top of the page. Immediately below the style, you have a web control (such as a Wizard control) that contains the bulk of the content. You attempt to edit this user control in design view and all you see is an empty page. Here's a trivial example: Explanation Design view was originally created to handle full HTML pages where the "body" and "head"...
One of the things I love about working on the ASP.NET team is that the team is very focused on getting customer feedback. One of the ways we do this we need to ship bits early and often. While I think this is great, it does present some challenges in terms of helping customers find the right bits for their need. Scott Galloway has been doing some thinking about this and has a good conversation over on his blog . I encourage you to chime in! Where should the ASP.NET team release stuff? Read More...
In this example I will demonstrate a very simple call to the FlickR REST APIs from a Silverlight client. At the end we will end up with an app that looks like this: Part 1. Define some Silverlight UI Part 2. Show the local open file dialog support Part 3. Call the FlickR Service to find a picture Part 4. Use IsolatedStorage to preserve some local settings across runs Part 5. Skinning the UI You are welcome to also get the completed sample , and demo files Part 1. Define some Silverlight UI You can go back and look at the post on my End to End Silverlight Application post for the getting started. In Blend add a TextBox, and Button to the window and layout as shown. Be sure to give them some meaningful name...

As a part of creating a way for customers to directly communicate with the product team and get help if they are running into performance issues in Visual Web Developer 2008 or web-related features in Visual Studio 2008, the product team has created a public alias to report all performance related concerns about the product. The alias is vwdperf-at-microsoft-dot-com . Your performance issue can be a major blocker that prevents you from working with the app or a pet peeve that has annoyed you. You are also welcome to send in suggestions for performance enhancements in future releases. Now is a great time to send in your feedback. We are actively looking into addressing performance issues in the next release, and timely feedback will help us a...
