Argotic Syndication Framework 2007.3 Released: I am proud to announce the latest release of the Argotic Syndication Framework. This release provides ASP.NET developers with built-in support for some of the most common syndication features web sites utilize when publishing syndicated content. The framework now provides both server and client support of the Pingback and Trackback peer-to-peer notification protocols, as well as server and client support for  the XML-RPC communication protocol. Several ASP.NET web controls have been provided to make implementing automatic discovery of Pingback, Trackback, and syndication feeds a simple and pain-free process.
New features for this release:
