RabbitMQ asynchronous support

Question

Does the RabbitMQ .NET client have any sort of asynchronous support? I\'d like to be able to connect and consume messages asynchronously, but haven\'t found a way to do eith

Answer 1

Rabbit supports dispatching to asynchronous message handlers using the AsyncEventingBasicConsumer class. It works similarly to the EventingBasicConsumer, but allows you to register an callback which returns a Task. The callback is dispatched to and the returned Task is awaited by the RabbitMQ client.

var factory = new ConnectionFactory
{
    HostName = "localhost",
    DispatchConsumersAsync = true
};

using(var connection = cf.CreateConnection())
{
    using(var channel = conn.CreateModel())
    {
        channel.QueueDeclare("testqueue", true, false, false, null);

        var consumer = new AsyncEventingBasicConsumer(model);

        consumer.Received += async (o, a) =>
        {
            Console.WriteLine("Message Get" + a.DeliveryTag);
            await Task.Yield();
        };
    }

    Console.ReadLine();
}
