Making Magic xpa Work with Team Foundation Server (Magic xpa 2.x)
Microsoft has replaced the old Visual SourceSafe with a new product called Team Foundation Server (TFS) as their source control tool: http://en.wikipedia.org/wiki/Team_Foundation_Server
As it is SCC compliant (it is, after all, a Microsoft tool) it should work with Magic xpa.
However, using it with Magic xpa requires additional software.
To get Magic xpa to work with TFS you need to install MS Team Explorer (which is used to manage your TFS workspace, etc.) and the MSSCCI provider. The provider is downloadable from MSDN at no cost. The provider is a small program required for non-Microsoft Visual Studio development environments, such as FoxPro and Magic xpa.
