title: Azure service bus read all messages at once using Azure.Messaging.ServiceBus
body: <p>I am using <code>Azure.Messaging.ServiceBus</code> nuget package to work with Azure service bus. We have created a topic and a subscription. The subscription has 100+ messages. We want to read all the message and continue to read message as they arrive.</p>
  <p><code>Microsoft.Azure.ServiceBus</code> package (deprecated now) provided <code>RegisterMessageHandler</code> which use to process every incoming message. I am not able to find similar option under <code>Azure.Messaging.ServiceBus</code> nuget package.</p>
  <p>I am able to read one message at a time but I have to call <code>await receiver.ReceiveMessageAsync();</code> every time manually.</p>
