title: Can't find build definition in TFS 2015
body: <p>I'm playing around with TFS2015 &amp; programmability. I've created a collection and some team projects in it. Furthermore I've created a few build definitions, but when I try to access it programmatically I get an exception, telling me the definition cannot be found.</p>
  
  <pre><code>Uri teamCollectionUri = new Uri("http://tfs-playground:8080/tfs/MyCollection");
  TfsTeamProjectCollection teamProjectCollection = new TfsTeamProjectCollection(teamCollectionUri);
  teamProjectCollection.EnsureAuthenticated();
  
  IBuildServer buildServer = (IBuildServer)teamProjectCollection.GetService(typeof(IBuildServer));
  
  var definition = buildServer.GetBuildDefinition("FakeService", "Build fake service");
  </code></pre>
  
  <p>But when I check the web UI I see that build definition right there. What am I missing here?</p>
  
  <p>Edit:</p>
  
  <pre><code>var builds = buildServer.QueryBuildDefinitions("FakeService")
  </code></pre>
  
  <p>Doesn't return any build definitions either ?!?</p>
