Simple implementation of RabbitMQ consumer and sender.


  • Sender implementation
  • Multiple consumer instances supported
  • Multiple processing options for received messages
  • Random expiration for messages sent to an holding queue (depending on the processing option)
  • TLS connection support
  • Limiter for message processing
  • Message properties for more advanced scenarios such as queues with support for priority messages, messages Headers, etc.

More details available on the project website.

Install-Package JN.RabbitMQClient -Version [version number]


First, you must create the RabbitMqConsumerService and then define delegates for ReceiveMessage, ShutdownConsumer and ReceiveMessageError. The service will start the required number of consumers when StartConsumers is called.

To use a retry queue, the method StartConsumers should be called with a RetryQueueDetails object.

Message processing instructions

OK - message is considered as successfully processed

RequeueMessageWithDelay - message is removed from the queue, but sent to a holding queue for later processing (typically with a dead letter configuration)

IgnoreMessage - message is removed from the queue and ignored

IgnoreMessageWithRequeue - message is rejected and sent back to the queue


Example for consumer and sender services:

    class Program
        static void Main(string[] args)
            Console.WriteLine("Hello World!");

            // consumer

            // you can also use extensions AddConsumersService() and AddSenderService() (in namespace JN.RabbitMQClient.Extensions)

            var consumerService = new RabbitMqConsumerService(GetBrokerConfigConsumers());

            consumerService.ReceiveMessage += ReceiveMessage;
            consumerService.ShutdownConsumer += ShutdownConsumer;
            consumerService.ReceiveMessageError += ReceiveMessageError;
            consumerService.MaxChannelsPerConnection = 5;
            consumerService.ConsumersPrefetch = 2;
            consumerService.ServiceDescription = "test consumer service";

            consumerService.StartConsumers("my consumer");
            // sender

            var senderService = new RabbitMqSenderService(GetBrokerConfigSender());

            IMessageProperties properties = new MessageProperties { Priority = 3 };

            var result = senderService.Send("my message", properties);

            Console.WriteLine($"Send result: {result.Success}");
            Console.WriteLine(result.ReturnedObject != null
                ? $"Queue details. ConsumerCount: {result.ReturnedObject.ConsumerCount}; MessageCount: {result.ReturnedObject.MessageReadyCount}"
                : $"Unable to obtain queue details. Reason: {result.ErrorDescription}");

            Console.WriteLine("Press any key to exit...");
