Rob Conery, creator of SubSonic, and the ASP.Net MVC Store Front video series has released an early prototype of a Visual Studio 2008 add-in called the SubSonic MVC Scaffold Addin. Let me point out right away that there is no dependency on SubSonic itself, rather this add-in uses Linq2Sql, although Rob says a SubSonic plug-in is on the drawing board.
Not to rehash his announcement, but basically this add-in takes a Linq2Sql class, and generates some views (view, edit, list), and a controller based on the class. This is meant as a quick start kind of thing, not a full fledged commercial web site generator.
I encourage you to visit his blog post and watch the video he has prepared, it does an excellent job of showing you what the Scaffold does. Here are some of my take-away's:
