The Patterns & Practices team's J.D. Meier posted that Beta 1 of the "Team Development with Visual Studio Team Foundation Server" guide is now available on the CodePlex community site.
Here is the chapter listing:
A good resource of industry practices and recommendations for those of you using or considering using Team Foundation Server.
Also on CodePlex, the Visual Studio Team System Rangers team announced availability of a preview of the Project Server 2007 VSTS Connector:
The Visual Studio Team System Project Server 2007 Connector is designed to integrate the project management capabilities of VSTS with Project Server 2007. It's been developed by the Visual Studio Team System Rangers in response to significant customer demand for a connector solution. Future versions of Team System will have native integration with Project Server, in the meantime this Connector solution is the best way to integrate the two Microsoft products.
