My good buddy Faisal has moved from MSBuild to ADO.NET. Specifically, he's the Program Manager for LINQ to SQL and the Object Service for Entity Framework. He says you'll hear a lot more from him on these things, but of course if past history is any indication his blogging will be short lived :)

Either way, I'm still waiting for him to convince me why I should LINQ instead of SubSonic. The only issue we're really having now with SubSonic is with the JOIN story, and they're supposedly prototyping stuff to address this in the next build.
