In this screencast, I show you how easy it is to expose RSS and Atom feeds using the new Web Programming Model (REST) features, classes in the new System.ServiceModel.Syndication namespace, and LINQ to SQL in the .NET Framework 3.5.  Then, you will see how you can use classes from the System.ServiceModel.Syndication namespace to consume RSS and Atom feeds using Silverlight 2.
