title: How can I forcibly close a TcpListener
body: <p>I have a service which communicates through tcpListener.
  Problem is when the user restarts the service - an "Address already in use" exception is thrown, and the service cannot be started for a couple of minutes or so.</p>
  
  <p>Is there's any way of telling the system to terminate the old connection so I can open a new one? (I can't just use random ports because there is no way for the service to notify the clients what is the port, so we must depend on a predefined port)</p>
