A powerful and extensible .NET web content syndication framework for RSS, Atom, OPML, APML, BlogML, RSD and more. The Argotic Syndication Framework is a Microsoft .NET class library framework that enables developers to easily consume and/or generate syndicated content from within their own applications. The framework makes the reading and writing syndicated content in common formats such as RSS, Atom, OPML, APML, BlogML, and RSD very easy while still remaining extensible enough to support common/custom extensions to the syndication publishing formats. The framework includes out-of-the-box implementations of the most commonly used syndication extensions, network clients for sending and receiving peer-to-peer notification protocol messages; as well as HTTP handlers, modules, services and controls that provide rich syndication functionality to ASP.NET developers.
