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 ensure that the subscription client processes all messages.
Which code segment should you use?

  • A. await subscriptionClient.AddRuleAsync(new RuleDescription(RuleDescription.DefaultRuleName, new TrueFilter()));

  • D. subscriptionClient.RegisterMessageHandler(ProcessMessagesAsync, messageHandlerOptions);

Selected Answer: D
D. subscriptionClient.RegisterMessageHandler(ProcessMessagesAsync, messageHandlerOptions); The RegisterMessageHandler method is used to start processing messages that have been sent to the Service Bus Topic. It takes two parameters: a function delegate that defines the processing of messages, and an options object that defines the settings for message processing. This is the method that actually starts the message pump and begins receiving and processing messages.

Old library : Microsoft.Azure.ServiceBus v5.2.0 I think nowadays (Azure.Messaging.ServiceBus v7.11.0) you simply would use : processor = client.CreateProcessor(queueName, new ServiceBusProcessorOptions()); processor.ProcessMessageAsync += MessageHandler; Still : the anwer is correct

Agreed on D when we use Microsoft.Azure.ServiceBus package. Furthermore, with the new version (Azure.Messaging.ServiceBus), we use a processor to receive/handle messages. https://docs.microsoft.com/en-us/azure/service-bus-messaging/service-bus-dotnet-get-started-with-queues#add-the-code-to-receive-messages-from-the-queue
