title: Azure Service Bus Queue processing messages asynchronously in parallel
body: <p>I create a windows forms program listening on an Azure Service Bus queue and it executes a long process for each received brokeredMessage :</p>
  
  <pre><code>QueueClient Client = QueueClient.CreateFromConnectionString(ConfigurationWrapper.QueueConnectionString, ConfigurationWrapper.QueueName);
  
              // Configure the callback options
              OnMessageOptions options = new OnMessageOptions();
              options.AutoComplete = false;
              options.AutoRenewTimeout = TimeSpan.FromMinutes(1);
  
  
              // Callback to handle received messages
              Client.OnMessageAsync((message) =&gt;
              {
                    message.Complete();
                  //big jobs put 10 minutes
                 Task t = Task.Factory.StartNew(() =&gt; DoAVeryLongJob(message));
  
                 return t;
              }, options);
  </code></pre>
  
  <p>If I send 2 messages with 2 seconds of interval in this queue, the program process the first message (calling DoAVeryLongJob which takes 10 minutes) and the second message will be processed at the end of the the first call (10 minutes after).  What I want is for these messages to be processed in parallel.</p>
  
  <p>Is it possible to process queue messages in parallel?</p>
