REST in Windows Communication Foundation (WCF)
Preview 2 posted to CodePlex, adding new client capabilities that we think should really make client-side REST development easier. Chief among the new functionality included in Preview 2 is a new class that provides a staged pipeline model for requesting resources over the web. Using this new HTTP client class allows the developer to plug into the various stages of communication to handle custom authentication, caching, and fault handling outside of the client’s application logic.
