MassTransit is a free, open-source distributed application framework for .NET. MassTransit makes it easy to create applications and services that leverage message-based, loosely-coupled asynchronous communication for higher availability, reliabililty, and scalability.

Getting started with MassTransit

In order to get started with MassTransit, you can have a look at the documentation, which is located at http://docs.masstransit-project.com/.

Simplest possible thing:

install-package MassTransit.RabbitMq then;

// Message Definition
class MyMessage
    public string Value { get; set; }

// Code Snippet for Console Application 
var bus = Bus.Factory.CreateUsingRabbitMq(sbc =>
    var host = sbc.Host(new Uri("rabbitmq://localhost/"), h =>

    sbc.ReceiveEndpoint(host, "my_queue", endpoint =>
        endpoint.Handler<MyMessage>(async context =>
            await Console.Out.WriteLineAsync($"Received: {context.Message.Value}");

    bus.Publish(new MyMessage{Value = "Hello, World."});


You will also need to set up RabbitMQ;

  1. Install Erlang using the installer. (Next -> Next ...)
  2. Install RabbitMQ using the installer. (Next -> Next ...) You now have a RabbitMQ broker (look in services.msc for it) that you can log into using guest, guest. You can see message rates, routings and active consumers using this interface.

Please note

You need to add the management interface before you can login. First, from an elevated command prompt, change directory to the sbin folder within the RabbitMQ Server installation directory e.g. %PROGRAMFILES%\RabbitMQ Server\rabbitmq_server_3.5.3\sbin\

Next, run the following command to enable the rabbitmq management plugin:

rabbitmq-plugins.bat enable rabbitmq_management
