title: Is Visual Studio 2012 csproj backward compatible with 2010?
body: <p>The question is if can I use safely Visual Studio 2012 to edit projects properties, add and remove solutions, references, all related to NET 4.0 Framework.</p>
  
  <p>I remember in the past some files might be "corrupted", while Visual Studio 2010 changed some Visual Studio 2008 csproj information (xml file).</p>
  
  <p>If some tags are added/removed in VS2012, then the csproj would be incompatible to VS2010 developers.</p>
  
  <p>Does anyone have some information if it is safe to use this new IDE without damaging files? 
  Are VS2012 csprojs "backward compatible" with VS2010?</p>
