After doing this a few times I thought I'd write down the process:

  1. Goto the folder containing the solution files and delete the following:
    • mssccprj.scc
    • MyProject.vssscc
    • vssser.scc
  2. Open the MyProject.sln in your text editor and remove the following section:
    • GlobalSection(SourceCodeControl) = preSolution
    • ...
    • EndGlobalSection
  3. Goto the folder(s) containing the project files and delete the following:
    • MyProject.vbproj.vspscc
    • mssccprj.scc
    • vssver.scc
  4. Open the *.proj file(s) and remove the following:
    • SccProjectName = "SAK"
    • SccLocalPath = "SAK"
    • SccAuxPath = "SAK"
    • SccProvider = "SAK"
    Now open up your solution and you should be Source Control free.
