title: Howto resolve... Visual Studio Source Control notification "Projects have recently been added to this solution"
body: <p>After some use Visual Studio 2008 when opening a solution that is checked into Visual Studio Team Foundation will pop up a dialog saying:</p>
  
  <blockquote>
    <p>Projects have recently been added to this solution.  Do you want to get them from source control?</p>
  </blockquote>
  
  <p>This happens every time the solution is loaded (even if no projects have been added).  The only way I have found to remove this minor annoyance is to completely rebuild the SLN file.</p>
  
  <p>Has anyone found a better/simpler way?</p>
