public async Task StartConsuming(IMessageBusConsumer consumer, MessageBusConsumerName fullConsumerName, CancellationToken cancellationToken)
        {
            var queueName = GetQueueName(consumer.MessageBusConsumerEnum);

            using (var model = _rabbitConnection.CreateModel())
            {
                // Configure the Quality of service for the model. Below is how what each setting means.
                // BasicQos(0="Don't send me a new message until I’ve finished",  _fetchSize = "Send me N messages at a time", false ="Apply to this Model only")
                model.BasicQos(0, consumer.FetchCount.Value, false);
                var queueingConsumer = new QueueingBasicConsumer(model);

                model.BasicConsume(queueName, false, fullConsumerName, queueingConsumer);


                var queueEmpty = new BasicDeliverEventArgs(); //This is what gets returned if nothing in the queue is found.

                while (!cancellationToken.IsCancellationRequested)
                {
                    var deliverEventArgs = queueingConsumer.Queue.DequeueNoWait(queueEmpty);
                    if (deliverEventArgs == queueEmpty)
                    {
                        // This 100ms wait allows the processor to go do other work.
                        // No sense in going back to an empty queue immediately. 
                        // CancellationToken intentionally not used!
                        // ReSharper disable once MethodSupportsCancellation
