Today we released a patch for VS 2008 SP1 and Team Explorer 2008 SP1 to be able to connect and use both the Team Foundation Service preview (http://tfspreview.com) and Team Foundation Server 2012.  You can download it here.

While we are on the subject of updates, the patch for Visual Studio 2010 SP1 and Team Explorer 2010 SP1 is available here.  Team Explorer Everywhere is available on the Eclipse Marketplace, TFS Plug-in for Eclipse.

Enjoy!
