error - One or more projects in the solution were not loaded correctly

Question

In VisualStudio2010 I changed the name of the project and the name of the solution. When I try to open the solution I get this error:

One or more projects in the solution were not loaded correctly.

Any idea why I get this error?And how to fix it?

Answer 1

Try opening the .csproj file in notepad and making sure all references and paths are correct.

Answer 2

In my situation, I had the GlobalSection duplicated in my solution. I'm using TFS and sometimes it has trouble to merge configuration from multiple developers at the same time.

Open your Solution (.sln) in NotePad++ and look up for this tag and remove one from the duplicated.

GlobalSection(TeamFoundationVersionControl) = preSolution

You may need to readd the last projects to the solution though.
