title: using AppDomain.DoCallBack() asynchronously
body: <p>I am trying to call DoCallBack for multiple AppDomains, but it is not asynchronous. Is there a way to make the calls asynchronous? Here is what I am attempting to do: </p>
  
  <pre><code>        var appDomain1 = System.AppDomain.CreateDomain("event1");
          var appDomain2 = System.AppDomain.CreateDomain("event2");
  
          Console.WriteLine("Executing appDomain1");
          appDomain1.DoCallBack(new CrossAppDomainDelegate(Event));
          Console.WriteLine("Executing appDomain2");
          appDomain2.DoCallBack(new CrossAppDomainDelegate(Event));
  </code></pre>
  
  <p>I am attempting to execute the method "Event" in multiple appDomains asynchronously.</p>
