As I've mentioned, we're always looking at ways to connect Visual FoxPro and Visual Studio. More and more of our VFP customers are also using .NET for various purposes.
At PDC, John Miller (jMM) asked me if we'd be hooking up VFP and Team Foundation Server - particularly for source code control. Well, in the latest beta of the MSSCCI, that connectivity works. Andrew Coates has the information on how to set things up (make sure to scroll down to the end - some of the information comes after the sidebar).
So now, those of you using Team System can use work item tracking (bugs, features, etc.) and source code control in your VFP application development efforts.
