wcf connection closed notification

Question

I am setting up a nettcp WCF connection between a client and a server as a reliable session with a 7 day timeout. The client is monitoring a process on the server. Most of the activity is the service raising callbacks to the client. If the service crashes, how can the client detect this and display a "connection failed" message? Do I need to send some kind of keep alive message from the client to the server on a regular basis, or is there some event I can listen to on the client?

My binding code is:

     NetTcpBinding binding = new NetTcpBinding();
     var reliableSession = binding.ReliableSession;
     reliableSession.Enabled = true;
     reliableSession.Ordered = true;

Try subscribing to the Closed event of the client or channel. See CommunicationObject events.
