A company is implementing a publish-subscribe (Pub/Sub) messaging component by using Azure Service Bus. You are developing the first subscription application.
In the Azure portal you see that messages are being sent to the subscription for each topic. You create and initialize a subscription client object by supplying the correct details, but the subscription application is still not consuming the messages.
You need to complete the source code of the subscription client
What should you do?
The code to receive messages must include setting up a message handler. The subscriptionClient.RegisterMessageHandler method is used to register a message handler and to continuously begin a new thread to receive messages, thus enabling the application to consume messages from the subscription. This ensures that any incoming message to the subscription is processed by the defined handler asynchronously.
