Microsoft recently unveiled a new Silverlight 4 based Facebook client, demonstrating a rich out-of-browser POC (Proof of Concept) in the familiar context of Facebook. The client is available for both Windows and Mac OS X. Those who saw the keynote of ScottGu during PDC 09, may recollect that an announcement related to this application was made then.
