title: .NET Outlook Add-in and WCF/Inter-process communication
body: <p>I need a tip/advice/recommendation.</p>
  
  <p>I'm finishing up a Outlook Add-in developed in C#.
  I would like this add-in to communication with another application (let's call it Client.exe).</p>
  
  <p>Client.exe and the add-in will always be running on the same computer. 
  Client.exe is a single instance application.</p>
  
  <p>What would be the easiest/most convenient way for me to allow the Add-in to communicate with the Client.exe?<br/>
  Would that be WCF? <br/>
  Any good resource you can recommend?</p>
  
  <p>Thanks in advance!</p>
