title: ExecutionTimer.cs not found when stepping into code
body: <p>I am writing some tests using XUnit framework and have to use some external code referenced through a dll.</p>
  <p>When I try to step into the method call, <code>helper.GetEntity()</code>, I get the following window and the execution exits.</p>
  <pre><code>[Fact]
  public void PassingTest()
  {
      var datapointJson = File.ReadAllText(@&quot;sample.json&quot;);
      dynamic datapointObject = JsonConvert.DeserializeObject(datapointJson);
  
      // This is referenced from a different project in the same solution.
      var helper = new Helper.Actions();
      var studentEntity = helper.GetEntity(&quot;tom&quot;);
  }
  </code></pre>
