I recently created a small 10 minute recording on how to create a WCF RESTful service. This screen cast has been published on Dime Casts .NET here. This is part 1 of the series in which I go into how to create a WebGet based WCF RESTful service. This screen cast is a video extension of the post I wrote here. At a high level, this screen cast is an introduction to the RESTful capabilities of WCF. In another future (yet to be recorded) Dime Cast I will go into how to utilize WebInvoke attribute to perform POST operations against the REST web service.
