I had run into this problem before.
- I have my Visual Studio 2008 options set to reload the previously loaded solution on startup.
- I use Subversion.
- I use AnkhSVN as my SVN provider in Visual Studio 2008.
If I launched Visual Studio 2008 with a particular solution loaded when I last closed VS, I would receive a “Source control provider could not be found” error.
However… if I just launched it via double-clicking on the .SLN file in my file system, no error!!!
OK – so I did a quick diff on a solution that I knew worked fine. Both had the expected source control provider information embedded:
SccProjectName = "Svn" SccAuxPath = "Svn" SccLocalPath = "Svn" SccProvider = "SubversionScc"
However there was a difference.
The solution that did not generate the error message also contained the following block in the “Global” section:
GlobalSection(SubversionScc) = preSolution Svn-Managed = True Manager = AnkhSVN - Subversion Support for Visual Studio EndGlobalSection
Which somehow got generated in one solution, but not the one causing problems. Once I copied the block from one solution to the other, the error message ceased to be shown on launch of VS2008.
