When I try to open a solution, I get a "The project file 'c:\...csproj' cannot be opened. The project type is not supported by this installation." error. I can create new .csproj files and open them just fine. I've looked on the web and the only solution I've seen is to open the VS command prompt and enter "devenv.exe /resetskippkgs", but this does not solve the issue.

Does anyone have any other idea why I could not open this project?
