How to remove Source Control Binding from Visual Studio Project

If your project has been binding with TFS before, and you want to open the project locally, you will get following annoying information: The team foundation server http://some-tfs-server/ is currently not available, The solution will be opened locally. To remove the annoying information, deleted the .suo next to the .sln file, and then opened the .sln file in Notepad and deleted this entire section:

GlobalSection(TeamFoundationVersionControl) = preSolution
    SccNumberOfProjects = 2
    SccEnterpriseProvider = {xxxxx}
    SccTeamFoundationServer = http://some-tfs-server/
    SccLocalPath0 = .
    SccProjectUniqueName1 = xxDemo\\xxDemo.csproj
    SccProjectName1 = xxDemo
    SccLocalPath1 = xxDemo
EndGlobalSection

If you can connect to the TFS, you just want to simply unload the project from the source control server, go to File -> Source Control -> Change Source Control and then unbind and/or disconnect all projects and the solution.

This should remove all bindings from the solution and project files. (After this you can switch the SCC provider in Tools -> Options -> Source Control -> Plug-in Selection).

The SCC specification prescribes that all SCC providers should implement this behavior including VSS, TFS, etc.
