"Unspecified Error" when binding a project to sour

[Tonya]

You may receive an "Unspecified Error" message when binding your project to source control (from within the Change Source Control dialog). This error message could appear when both the solution (*.sln) and the project (*.csproj) files are NOT selected at the same time. To resolve this issue, unbind any of the files that are already bound and close the change source control" dialog. Reopen the dialog, select both of the files concurrently and you should now be able to rebind the project without problems.
