Easly reading RSS Feeds or ATOM Feeds with System.ServiceModel.Syndication in C# with .net 3.0

Less code lines are almoast not possible! But one leak is available; the load method always download the full items and there is no option only to download item headers.

The formatted version is also available at my website: http://www.ronischuetz.com/code/reading_rss_atom_feeds.html
