Microsoft has released Visual Studio Team Foundation Server MSSCCI Provider. With this provider, you can access Team Foundation Server Version Control features from VS.NET 2003 and Visual Studio 6.0. I feel this is the best move from Microsoft in pushing VSTS to all the developers as most of the developers are still using Visual Studio and VS.NET 2003. But currently, this supports only version control features only along with support for work item integration to associate work items with change sets, and check-in notes.
