title: Send message from one running console app to another
body: <p>I have one console app that is doing some lengthy syncing to an ftp server.<br>
  Another console app prepares a local filesystem with some needed updated files.<br>
  Then the second one will wait for the first one to finish before swapping a final directory name so it becomes visible on the web.</p>
  
  <p>I searched for the best way to make the syncing app to communicate to the second app that it's finished it's job. It looks like <a href="http://msdn.microsoft.com/en-us/library/aa365574(VS.85).aspx#base.using_data_copy_for_ipc" rel="noreferrer">Using Data Copy for IPC</a> is the best suited solution for this.  </p>
  
  <p>Question is two fold:</p>
  
  <ul>
  <li>Am I right? Is there a more straight forward way to get to the same result?</li>
  <li>Is there a managed (.net) way to do this?</li>
  </ul>
