Programatically start and stop a WCF service

// Create the ServiceHost.

using (ServiceHost host = new ServiceHost(typeof(HelloWorldService), baseAddress))

    host.Description.Behaviors.Add(smb);

    // Open the ServiceHost to start listening for messages. Since
    // no endpoints are explicitly configured, the runtime will create
    // one endpoint per base address for each service contract implemented
    // by the service.
    host.Open();

    Console.WriteLine("The service is ready at {0}", baseAddress);
