title: Sharing a C++ solution between Visual Studio 2010 and 11
body: <p>Me and my partner are both sharing a c++ solution via subversion.</p>
  
  <p>He is using Visual Studio 11 and I am using Visual Studio 2010.</p>
  
  <p>After the first time he commited and i updated, i get the following error:</p>
  
  <p><code>Error  31  error MSB8008: Specified platform toolset (v110) is not installed or invalid. Please make sure that a supported PlatformToolset value is selected.</code></p>
  
  <p>also, in header files i get the following error on <code>#include &lt;stdio.h&gt;</code>:</p>
  
  <p><code>error: cannot open source file "stdio.h"</code></p>
  
  <p>I am guessing this is a compatibility issue. How can we resolve this?</p>
