The recording for the webinar I did on October 4th about getting started with REST services and the WCF Web API is available on the DevelopMentor website. You can watch the video stream from here or download the file, even in mobile format, from here. And besides this screencast there are a lot of other interesting videos to watch there
In this session Maurice de Beijer will show you how to get started building REST services. He will explain how REST embraces the strengths of HTTP to create very scalable services. He will show how REST services differ from SOAP services and what the pro’s and con’s of each approach is. He will demonstrate building REST services using the new WCF Web API.
