WCF : in netTcpBinding do we need to use keepalive message

Question

Hi

If we use netTcpBinding  in WCF, do we need keep alive message from server to client, to keep client connection for longer or not?

by just enabling reliable session and making request and response timeouts to large is enough?

i am sending message from server to client in callback method to keep client alive and avoiding fault channel.

Hi Prabhakar26,

Based on your description, I know that you want to keep your TCP connection live as long as clients need it, then we can use the reliable session, but it will time out just like any other session. so if you want your sessions to be endless, you need to crank up the timeouts on the session.

Besides, the following threads may give your some idea:

So don't need to provide a dummy method in server.

presently i am using dummy method in server and calling from client to keep connection alive.
