In order to remove source control from a sln you must do the above. From my experience, everything else maybe fail.
Remove all
.vsscc
,.vspscc
and.scc
files from ALL folders.ReadOnly false all files.
- Open sln with an editor and remove
GlobalSection(SourceCodeControl) = preSolution
Section. - Open each prj with an editor and remove all tags that starting with
Scc
.
