title: How do I open a csproj with ProjectTypeGuids 349c5851-65df-11da-9384-00065b846f21?
body: <p>I have Visual Studio 2012 Professional. When I try to open a particular csproj I get an error message</p>
  
  <blockquote>
    <p>The project type is not supported by this installation.</p>
  </blockquote>
  
  <p>It doesn't say what 'project type' the project is, nor what I need to install to be able to open it.</p>
  
  <p>On inspecting the <code>.csproj</code> file, I see the lines</p>
  
  <pre><code>&lt;ProductVersion&gt;9.0.30729&lt;/ProductVersion&gt;
  &lt;ProjectTypeGuids&gt;{349c5851-65df-11da-9384-00065b846f21};{fae04ec0-301f-11d3-bf4b-00c04f79efbc}&lt;/ProjectTypeGuids&gt;
  </code></pre>
  
  <p>So <strong>what do need I install</strong> to be able to open this project? Please provide a link!</p>
