ASP.NET MVC 2 Preview 1
The second version of ASP.NET MVC is already underway (it’s on the same type of frequent release schedule as Silverlight). MVC is a model-view-controller framework on top of the existing ASP.NET runtime that separates display and application logic as well as makes test-driven development of ASP.NET applications easier. MVC could be used with a variety of types of web applications but is frequently associated with REST applications.
The MVC 2 Preview 1 runs on Visual Studio 2008 with .Net 3.5 SP1 and you can have both MVC 1 and MVC 2 installed at once.
If you’re not looking for a preview release, you can get the original ASP.NET MVC 1.
