Working Scenario:

1. Post Msg1 to topic

1. Post Msg1 to topic
2. Read Msg1 from topic through subscriber, but I'm not marking as complete.(Still on Queue)
3. Post Msg2 to topic

      if (namespaceManager.TopicExists(topic))
                   {
                       var lstOfValues = new List<SITConfirmation>();
                       SubscriptionClient Client = SubscriptionClient.CreateFromConnectionString(ConfigurationManager.ConectionString(), topic, subscriber);
                       IEnumerable<BrokeredMessage> messages = await Client.ReceiveBatchAsync(10, TimeSpan.FromMilliseconds(500));
                    }
   

Answer 1

With ReceiveBatchAsync(messageCount) you're not promised to get the exact number of messages requested. Gateway could have all the messages or not. It will return whatever it has (gateway might have less/more/same number of messages that are actually stored on the broker entity).

From the documentation:

As this is an approximation, fewer or more messages than messageCount may be returned.
