I have multiple projects in our solution that is in our TFS 2010 repository. I\'ve added about 5 new projects to this solution in recent days.
I have found that for one
I was faced with the same issue but the solution is slightly different than those mentioned so far. My project's contents were checked in but the project itself was not. The project's bindings were valid.
In the Team explorer's Source Code Explorer, the project files were greyed out. After a get-latest, TFS opened the Merge Conflicts screen where I could choose to keep the local copy.
After this, the project was part of TFS.
