title: Where is Microsoft.VisualStudio.TeamFoundation.VersionControl.dll in Visual Studio 2015
body: <p>I'm migrating my own TFS logging extension to VS 2015 and run into many dependency issues. Most of them I was able to get rid off by installing <a href="https://www.nuget.org/packages/Microsoft.TeamFoundationServer.ExtendedClient/" rel="nofollow">Microsoft.TeamFoundationServer.ExtendedClient</a> nuget package.</p>
  
  <p>However there's still one missing reference, the <code>VersionControlExt</code>class</p>
  
  <pre><code>versionControlExt =
                      _applicationObject.GetObject("Microsoft.VisualStudio.TeamFoundation.VersionControl.VersionControlExt")
                      as VersionControlExt;
  </code></pre>
  
  <p>According to documentation, it is located in <code>Microsoft.VisualStudio.TeamFoundation.VersionControl.dll</code>, but I can't find this file at all. Does anyone know where to get it from or how to change the above code to get it working with VS 2015?</p>
  
  <p>I'm using Visual Studio 2015 Professional, 14.0.23107.0 D14REL version.</p>
