ASP.Net 3.5 MVC Framework

As the name suggests, MVC (Model View Controller) framework gives you the ability to separate Data and DataBinding logic from the actual Presentation of data quite easily but the biggest win is that you can test the controller entirely independent of the view so that you can perform real unit tests that might be bit harder to perform on the web forms.
