             try {
                 WSHttpBinding binding = new WSHttpBinding ();
                 EndpointAddress address = new EndpointAddress ("https://192.168.0.1/Service/Service.svc");
                 binding.Security.Mode = SecurityMode.Transport;
                 
                 factory_1 = new ChannelFactory<IService> (binding, address);
                 factory_1.Credentials.ServiceCertificate.Authentication.CertificateValidationMode = X509CertificateValidationMode.None;
                 channel_1 = factory_1.CreateChannel ();    
                 resultstr = channel_1.GetData(10);
                         yield return new WaitForSeconds (5);
                 Debug.Log(resultstr);

             } catch (Exception e) {

I don't really know much about WCF, but my guess would be that the GetData call is a synchronous call so it waits until the data is available before it returns. Coroutines are a form of cooperative multitasking, so if the coroutine doesn't run quickly between yield statements, everything freezes.

You should be able to call an asynchronous method with WCF, so the call returns immediately, then the coroutine can loop and poll with yields inside the loop. Or use a callback or something, but that should give you something to google for.

I was going to point to $$anonymous$$icrosoft's async example, but I'm not 100% sure that will work in the version of $$anonymous$$ono used by Unity. It's worth giving it a shot though.

Otherwise you might need to use threading, or use Unity's WWW class to grab the data. There are JSON serializers that can then turn it into a class for you.
