ASP.NET MVC templates were not shipped as part of Visual Studio 2010 Beta. But it will ship “in the box” when Visual Studio 2010 is released. Today you can download the update for MVC from ASP.NET MVC For Visual Studio 2010 Beta 1. It contains the tooling and assemblies for ASP.NET MVC 1.0, but with the placeholder version 1.1.
See MVC 1.1 for VS2010 Beta 1 Released on Jason Zander’s WebLog for additional details.
ASP.NET MVC is a free, fully supported, web framework that provides total control over your HTML and URLs, enables rich AJAX scripting, and facilitates test driven development.
