Exception on System.ServiceModel.AddressAlreadyInUseException (ChannelListener)
I have an application which tries to host WCF service in a separate process.
So in my application, in the main process it has WCF service (called MainService), then in MainService, it starts another service by creating new Process() and the executable in the children process will use ServiceHost() to create a new WCF service.
When the MainService is stopped by using ServiceHost.Close(), and I use "netstat -a" at commandline and I saw the tcp listener for the MainService port is still alive. However, if I kill all child processes, then it's gone. If I don't kill the child process, and I try to restart the MainService, I will get error:
System.ServiceModel.AddressAlreadyInUseException: There is already a listener on IP endpoint 0.0.0.0:10100. Make sure that you a

I don't know what I am doing wrong here. I don't know what I miss to set in WCF. I try to find something in WCF binding that match with SO_reuseAddr in winsock.
In WCF, how can I find out if any channel is already in used? or How can I set the channel listener to reuse the port without using portSharingEnable?
Thank very much in advance for all your help
Anna
