We had SQL Server 2008 r2 project. Then we converted it to SSMS 2012 format. Now I can't open the converted project. I am getting an error
C:\Views.ssmssqlproj : error : Unexpected error encountered. It is recommended that you restart the application as soon as possible.
Error: No such interface supported File: vsee\internal\inc\vscomptr.inl Line number: 259
The older project was using SourceSafe 6. I wonder if it is the reason. SQL Server Management Studio 2012 doesn't support SourceSafe 6 anymore.
