Earlier this week a new preview for the ASP.NET Model-View-Controller framework showed up on the web. For those of you that haven't heard of MVC before, it's a framework on top of the existing ASP.NET runtime that modernizes the ASP.NET development experience a bit in terms of separating display and application logic as well as making test-driven development of ASP.NET applications easier.
You can get the preview now as well as a variety of other resources.
