As my understanding, VS 2012 support ASP.Net web form project type. However, I get the following error when trying to open a web form project created by VS 2010:
Unsupported This version of Visual Studio does not have the following project types installed or does not support them. You can still open these projects in the version of Visual Studio in which they were originally created. - MyApp No changes required These projects can be opened in this version of Visual Studio without changing them. They will continue to open in Visual Studio 2010 SP1 and in this version of Visual Studio.
Another web form project has been migrated to VS 2212 without any problem. Could anyone provide a tip on how to find the exact cause of the problem?
