The MVC framework for ASP.NET allows you to create applications that follow the model/view/controller architecture.  VS2010 Beta 1 did not have MVC built-in to the product but you can now download it here.  MVC will be included in the final release of the product.

After installation you will have MVC templates installed for both VB and C#:

Scott Guthrie has a fantastic walk through on MVC using the VS2008 product which is also be relevant to V2010 (modulo a few dialog changes here and there).

Enjoy!
