If you are looking for the online MSDN documentation, point your favorite browser to the Team Foundation Server Developer Center.

There will also come some new books on VS2010: Professional Visual Studio 2010 Team System: with Team Foundation Server 2010, but I think that the name of the book will still change. Martin Woodward also mentioned that he’s writing on a new Team Build book for VS2010 and I’m sure that there are others under construction. To be continued!
