title: Make A Delay For A Few Seconds
body: <p>I have been wondering how to make a delay. I have tried thread.sleep but it stops the project. I would want to do something like:</p>
  
  <pre><code>Form4 ss = new Form4();
  ss.Show();
  wait(4000) //4000 miliseconds
  ss.close();
  </code></pre>
  
  <p>I tried <code>await Task.Delay(4000);</code> but it said:
   I had the wrong return type
  Please help</p>
