title: ASP.NET MVC return empty view
body: <p>What is the most natural way to return an empty ActionResult (for child action)?</p>
  
  <pre><code>public ActionResult TestAction(bool returnValue)
  {
     if (!returnValue)
       return View(EmptyView);
  
     return View(RealView);
  }
  </code></pre>
  
  <p>One option I can see is to create an empty view and reference it at EmptyView... but may be there is any built-in option?</p>
