Facebook via Silverlight and WPF

There was a lot of buzz last week with Facebook’s Open Stream API announcement. There were many demos of applications leveraging the new API, one good one is Seesmic Desktop which I’ve been using as my Twitter client and now has Facebook integration. It's an Adobe AIR based application. On the home front, Microsoft took part in the Facebook event and showed off some very slick Silverlight and WPF clients leveraging the Facebook API. Both were technology demonstrations created in 72 hours by two teams of 3 developers. This post over on Team Silverlight has the details and a bunch of screenshots. In their Twitter stream they say that they will be publishing the source code for these very soon. Below is a TechCrunch video showing them in action.
