title: Cannot get VersionControlServer service from TFS
body: <p>I have a console application, which needs to download some files from source control (TFS). But when using the code below, the <code>VersionControlServer</code> service is null. Due to this, I cannot download the files I need.</p>
  
  <pre><code>TfsTeamProjectCollection tpc = TfsTeamProjectCollectionFactory.GetTeamProjectCollection(new Uri(UrlSite));
  tpc.EnsureAuthenticated();
  bool hasAuthenticated = tpc.HasAuthenticated; // true
  var versionControl2 = tpc.GetService&lt;VersionControlServer&gt;(); // null 
  var buildServer2 = tpc.GetService&lt;IBuildServer&gt;(); // successful initialization
  var workItemStore2 = tpc.GetService&lt;WorkItemStore&gt;(); // successful initialization
  </code></pre>
