title: Visual Studio 2012 The project type is not supported
body: <p>I am having trouble with a web application project that was originally created in VS 2010 and then imported by someone else within our team of 3 developers. The solution is a pretty complex MVC4 project with multiple projects.</p>
  
  <p>When I try and open the solution, I get the project not supported message for the MVC4 web application. All the other projects are class libraries and they load without any problem.</p>
  
  <p>I am the only one of the three who gets this error. Even more strangely, if I share my solution folder the other devs can open my solution without any problem.</p>
  
  <p>I have tried repairing the VS 2012 installation, but still get the error.</p>
  
  <p>I could try doing an uninstall / reinstall, but I am really curious as to why this is happening.</p>
  
  <p>I have looked in the CSPROJ file and found the VisualStudioVersion attribute set to 10.0. Surely this cannot be right?</p>
  
  <pre><code>  &lt;PropertyGroup&gt;
      &lt;VisualStudioVersion Condition="'$(VisualStudioVersion)' == ''"&gt;10.0&lt;/VisualStudioVersion&gt;
      &lt;VSToolsPath Condition="'$(VSToolsPath)' == ''"&gt;$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v$(VisualStudioVersion)&lt;/VSToolsPath&gt;
    &lt;/PropertyGroup&gt;
  </code></pre>
  
  <p>If anyone has any explanation for why this problem is occurring, I'd love to hear it!</p>
  
  <p>Thanks</p>
