This past Thursday the ASP.NET MVC feature team published a new "Preview 5" release of the ASP.NET MVC framework.  You can download the new release here .  This "Preview 5" release works with both .NET 3.5 and the recently released .NET 3.5 SP1.  It can also now be used with both Visual Studio 2008 as well as (the free) Visual Web Developer 2008 Express SP1 edition (which now supports both class library and web application projects). Preview 5 includes a bunch of new features and refinements (these build on the additions in "Preview 4" ).  You can read detailed "Preview 5" release notes that cover changes/additions here .  In this blog post I'm going to cover one of the biggest...

Silverlight 2 Beta2 was released today.  You can download both Silverlight 2 Beta2 and the Visual Studio and Expression Blend tools support to target it here . Beta2 adds a lot of new features (more details below), but is still a 4.6 MB download that takes less than 10 seconds to install on a machine.  It does not require the .NET Framework or any other software to be installed for it to work, and all features work cross-browser on both Mac and Windows machines.  These features will also be supported on Linux via the Moonlight 2 release. Silverlight 2 Beta2 supports a go-live license that allows you to start using and deploying Silverlight 2 for commercial applications. There will be some API changes between Beta2 and the final...

This morning we released the Preview 3 build of the ASP.NET MVC framework.  I blogged details last month about an interim source release we did that included many of the changes with this Preview 3 release.  Today's build includes some additional features not in last month's drop, some nice enhancements/refinements, as well as Visual Studio tool integration and documentation. You can download an integrated ASP.NET MVC Preview 3 setup package here .  You can also optionally download the ASP.NET MVC Preview 3 framework source code and framework unit tests here . Controller Action Method Changes ASP.NET MVC Preview 3 includes the MVC Controller changes we first discussed and previewed with the April MVC source release , along...

Earlier today we shipped a public beta of our upcoming .NET 3.5 SP1 and VS 2008 SP1 releases.  These servicing updates provide a roll-up of bug fixes and performance improvements for issues reported since we released the products last November.  They also contain a number of feature additions and enhancements that make building .NET applications better (see below for details on some of them). We plan to ship the final release of both .NET 3.5 SP1 and VS 2008 SP1 this summer as free updates.  You can download and install the beta here . Important: SP1 Beta Installation Notes The SP1 beta released today is still in beta form - so you should be careful about installing it on critical machines.  There are a few important SP1...

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...

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...

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...

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...

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

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...
