Now that I'm mostly caught up with reporting on sessions from PDC, I'll start talking a bit about the future of WCF that we announced during the conference.
The REST Starter Kit is actually something that is available now rather than coming in the next release of the framework. We had been thinking for a while about the state of REST support for the platform and decided to bring together guidance and samples for how to use this architectural style with WCF. The starter kit includes some experimental framework classes, Visual Studio templates, code samples, and documentation to better enable you to create applications in the REST style using WCF. Some of these resources are focused on REST itself, others are more broadly applicable to HTTP services, and still others deal with specific protocols that are often found together with REST applications, such as Atom.
There's no guarantee that any part of the starter kit will become part of the mainstream framework, but if you find something here that's useful, tell me about it so that we know which features you get the most value from. You can also tell me about things that we didn't include in the starter kit that you would have expected to see.
