A little about MVC:
The MVC framework enables you to easily implement the model-view-controller (MVC) pattern for Web applications. This pattern lets you separate applications into loosely coupled, pluggable components for application design, processing logic, and display.

To makes things easier, the release was accompany with a serious of nice videos given by Scott Hanselman. Even though this new framework is very new (and experimental I must add), there are some nice thing there that I’m sure will become a part of the next LINQ version.

I was especially impressed by the dynamic data support which simplifies your data management w/o too much effort. You can read more about the new package features here and to download it here. Try it, its cool.
