title: DispatcherTimer.Start() starts the Tick in a background thread?
body: <p>Does <a href="https://msdn.microsoft.com/en-us/library/system.windows.threading.dispatchertimer(v=vs.110).aspx" rel="nofollow"><code>DispatcherTimer</code></a> start a new thread?</p>
  
  <p>I noticed that the code example below is non-blocking:</p>
  
  <pre><code>//  DispatcherTimer setup
  dispatcherTimer = new System.Windows.Threading.DispatcherTimer();
  dispatcherTimer.Tick += new EventHandler(dispatcherTimer_Tick);
  dispatcherTimer.Interval = new TimeSpan(0,0,1);
  dispatcherTimer.Start();
  </code></pre>
  
  <p>So in this code example, will <code>Tick</code> (i.e. <code>EventHandler</code>) be executed on a different thread or will it be executed on the same thread that is setting up the <code>dispatcherTimer</code>?</p>
