I've gotten a lot of requests (internally and externally) for requests for resources on how to use the new WCF Web Programming Model features in .NET 3.5.

MSDN has a lot of great content on this stuff, but it's kind of sprinkled around in various places due to the way the MSDN table of contents is laid out.
