title: C# bi-directional IPC over stdin and stdout
body: <p>How can I connect two C# processes so they can communicate with each other over stdin and stdout?</p>
  
  <p>Like this:</p>
  
  <p>Process A --> stdout A --> stdin B ---> Process B</p>
  
  <p>Process A &lt;-- stdin A &lt;-- stdout B &lt;--- Process B</p>
