When developing those network hosting services (over HTTP or TCP), it is useful to get the IP address of the client-side callers/consumers so as to perform some counting or analysis work.

We can use the OperationContext.Current property to access those message properties in the service operation code. The following code snippet shows how to obtain the reference to message properties within service...
