title: Re-add missing project without having to re-add it to all projects referencing it
body: <p>Lets say you open a .NET solution (mine being VS 2010) after you just moved your entire folder to some new location locally.  Now one of the projects that was being referenced in that solution is not there and so when you launch VS, it naturally tells you that the project is missing and therefore as always you see the project greyed out in Solution Explorer.</p>
  
  <p>Ok, well I can't go re-add that project (specify a different path for where that project lives) unless I remove the missing project reference and then try to re-add it back to the solution.</p>
  
  <p>But how can I reassociate a project without losing all references in other projects that were referencing that missing project?  Is this possible?  Otherwise every time I re-add that missing project, I end up having to go through about 8 projects of mine that are referencing it and re-reference it for each one of those projects which is tedious.  I guess it makes sense since each project was referencing that missing project at that old path so it would break it there as well but is there an easier way to re-associate a project and references to that missing project without having to take 10 minutes every time to re-associate it all over the place if simply the path has changed?</p>
