One of the benefits of hosting a WCF service using IIS or WAS is that each automatically creates an instance of the ServiceHost class when a client calls the service. You simply need to specify what service the host should activate. You do this in a .svc file by setting the Service property of the ServiceHost directive. The endpoints are defined in the Web.config file.
