title: The name 'Thread' does not exist in the current context
body: <p>When I put this code <code>Thread.Sleep(2000);</code> it gives me the error:</p>
  
  <blockquote>
    <p>The name 'Thread' does not exist in the current context`. </p>
  </blockquote>
  
  <p>I already included the namespace <code>using System.Threading;</code>. See <a href="https://msdn.microsoft.com/en-us/library/d00bd51t%28v=vs.110%29.aspx" rel="noreferrer"><code>System.Threading.Thread.Sleep()</code> on MSDN</a>.</p>
