My friend Joe Gregorio(www.bitworking.org) writes a column on XML.com on Restful web. Joe has written lot of articles on REST. If you want to know what is REST I will recommend you read his first article on the topic at http://www.xml.com/pub/a/2004/12/01/restful-web.html.
Adoption of Windows Communication Foundation(WCF) is growing and many of you maybe interested in building REST services through WCF. The WCF REST Starter Kit is here to help you. :)
WCF REST Starter Kit is set of features, Visual Studio templates, samples and guidance that enable users to create REST style services using WCF. Previous release of the KIT focused on building server-side REST services, the new release adds features to 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.
