current OperationContext is null in WCF Windows Service

Question

I am trying to set up a Publish/Subscribe system using WCF and where the WCF server is in a Windows service. The binding is net.TCP. The service is providing a \"Subscribe

Answer 1

In the client code neither proxy created not channel factory. Service class instance is created as a class library.

You should consume service as below code

 ServiceCallback serviceCallback = new ServiceCallback();
 InstanceContext instanceContext = new InstanceContext(serviceCallback);

 var pubsubProxy = new PubSubProxy.WcfPublisherContractClient(instanceContext);
 pubsubProxy.Subscribe();

And when the service is running, OperationContext is created and you can access OperationContext.Current
