Services are needed to light up the Web, and Windows Communication Foundation (WCF) makes it possible to build RESTful services more quickly and easily than ever before by using the new WCF REST Starter Kit. In this session, we demonstrate using WCF to build a simple REST Service through to advanced REST concepts of Addressability, Scalability, and Security.
