wcf service port

I have two processes running on the same machine. Each process is hosting a WCF service to allow inter process communications asynchronously. As of now, I have assigned a fixed port 8731 and 9000 to the two wcf services. What if a customer machine has these ports taken up? How can i dynamically make the wcf client find the wcf service if I were to dynamically allocate an available port?

Thanks for your help in advance.

I am late on this post, but today we have better solution for this problem. There is a configuration endpoint known as listenUriMode(https://msdn.microsoft.com/en-us/library/system.servicemodel.description.listenurimode(v=vs.110).aspx), if we set this value to "Unique", it will bind hostname to port 0 which will ask OS to assign a free port.

Now client can know about the server port using WCF discovery(https://learn.microsoft.com/en-us/dotnet/framework/wcf/feature-details/wcf-discovery-overview).

I assume you're creating services in code. If you're afraid of the client not having those ports available, you should configure your endpoints using app.config. That way, if a client has an issue with a port, you can simply change their config file instead of recompiling your code.
