title: How to use VS 2015 MSBuild to build .vdproj
body: <p>With VS 2010 or 2013, We can use this command to build .vdproj project(VSI):</p>
  
  <pre><code>&lt;Exec Command="&amp;quot;$(ProgramFiles)\Microsoft Visual Studio 9.0\Common7\IDE\devenv.com&amp;quot; your.vdproj /build &amp;quot;Debug|AnyCPU&amp;quot;"/&gt;
  </code></pre>
  
  <p>But in vs 2015, the VSI is an extension of vs. And the similar command(9.0 => 14.0) will get an error.</p>
  
  <p>Anybody know how to solve it? </p>
