The WCF RSS Toolkit is a Windows Communication Foundation-based framework for generating RSS 2.0 and Atom 1.0 content feeds. Using this toolkit, developers can easily expose a service as an RSS or Atom feed. The toolkit supports exposing a service as an RSS 2.0 feed, Atom 1.0 feed and SOAP endpoint simultaneously. The toolkit can also be extended to support other wire formats.

Update:  This version has been updated to work in Visual Studio 2008 with the .NET Framework 3.5.  While this entailed several small changes from the CTP version, it also removes the need for the POX Encoding as that is available as part of WCF by default.  The POX Encoder code is left in the project but is not being used.  All of the samples have been updated as well.
