Starting a FB app today - which toolkit to use?

May 23, 2010 at 3:37 AM

If I were to start a Facebook app today, May 2010, which .NET toolkit should I use?  My app needs to live until December 31, 2010, and then I can take it down. 

I can't figure out what changes have been made upstream and how they affect all the toolkits out there.  For example, is the REST API going away?

I see the Facebook Graph Toolkit, but as of today there is no download available there.
