title: Converting C++ project from Visual Studio 2008 to Visual Studio 2010
body: <p>I have a C++ project developed with Microsoft Visual Studio 2008, that now I want to convert to Visual Studio 2010.</p>
  
  <p>I've opened the VS2008 solution with VS2010 and to run the default conversion. The conversion went alright, but then my project was "unloadable": Visual Studio shows it in the menu, but below it says "The project was unloaded", and there's no way to open it.</p>

  <p>What could I do?
  Why do the project result "unloaded"?
  Why does it refuse to open it?</p>
  
  <p>Many thanx to all</p>
  
  <p>[Edit] If I click on "reload project", here's what I get:</p>
