WCF: Communicating with the ServiceHost?

Hey

This one's bugging me. I'm building a WCF service so that I can issue work to multiple clients and retrieve results back on the server (wsDualHttpBinding with callbacks). The WCF service is hosted in a WPF application using a ServiceHost.

I am curious how I communicate with the service from within the WPF application? Would I have to connect to the endpoint like the clients would have to? Once the clients have registered their callback with the service, i'd like to be able to invoke those callbacks from within the WPF app.

Someone asked the same thing not long ago, see if their thread helps you at all: http://www.vbforums.com/showthread.php?t=584272

Ah, i missed that thread. That gave me an idea... Singleton.

Step 1: Set the service to a singleton (which is what i really want):

Code:

---

[ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Single, InstanceContextMode = InstanceContextMode.Single)]

---

Step 2: Set up the service

Code:

---


WCFService workService = new WCFService(controller);
ServiceHost host = new ServiceHost(workService);
host.Open();

---

Step 3: Call the service method

Code:

---

workService.CallMethod();

---

Thanks... the help is much appreciated. I feel silly for missing that. I didn't realise I could start the service with an instantiated object.

Glad I could help point you in the right direction :)
