title: How to open a VS2010 solution in VS2012 without migrating or changing any file?
body: <p>I work in a team who use Visual Studio 2010. I started using Visual Studio 2012 to work in our VS2010 solution. I understand that VS2012 can open a VS2010 solution and keep the compatibility with VS2010. However I noticed that VS2012 made changes to all the .sln, .csproj file. Plus every .datasource in the webreference folder &amp; a few .Designer.cs files. After these changes, VS2010 can still open the solution.</p>
  
  <p>However my concern is that when the other developers get the latest code, they will load a bunch of files which shouldn't be modified and they will be alarmed.</p>
  
  <p>I can't go through explaining that the modified files are OK or the modifications won't hurt anything... because I am supposed to be using VS2010.</p>
  
  <p>Is there a way to use Visual Studio 2012 and keep ALL the files untouched when opening for the first time? I guess using VS2012 in 100% VS2010 compatibility mode, if such thing exists.</p>
