title: Why is TFS ignoring a project in my solution?
body: <p>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.</p>
  
  <p>I have found that for one of the projects, that the project file itself will not check-in to TFS. All of the artifacts contained in this project are working fine; they are checked in and I can see them in the Team Explorer. But I cannot see the project file in Team Explorer, nor is their an icon next to the project in Solution Explorer that would indicate its checked in status. </p>
  
  <p>Also, clicking on any of the TFS related option in the context menu in Visual Studio results in those options being applied to the file contained in the project, not the actual project itself.</p>
  
  <p>Can this be remedied or do I have to create an entirely new project and add all of the artifacts from the old project back into it?</p>
