MassTransit RabbitMQ Aspire Client Extension

Overview

This package provides an Aspire client extension for seamlessly integrating MassTransit with RabbitMQ. It works with the Aspire.Hosting.RabbitMQ.AddRabbitMQ() method for hosting.

The name string should match the name used in Aspire.Hosting.RabbitMQ.AddRabbitMQ(), as it references the connection string.


Features

  • Configures MassTransit RabbitMQ integration for clients.
  • Automatically discovers and registers consumers, sagas, and activities.
  • Supports OpenTelemetry and Application Insights for monitoring.
  • Uses the same configuration format as the hosting environment for easy integration.
  • Multi-bus support to configure multiple RabbitMQ instances.

Usage

Installation

To install, add the extension to your client application using builder.Services in Startup.cs or Program.cs.

Example Usage

builder.AddMassTransitRabbitMq(
    "rmq",
    options => { options.DisableTelemetry = false; },
    consumers =>
    {
        consumers.AddConsumer<SubmitOrderConsumer>();
        consumers.AddConsumer<CancelOrderConsumer>();
        consumers.AddConsumer<UpdateOrderConsumer>();
    }
);

Multi-bus example

public interface ISecondBus : IBus;
builder.AddMassTransitRabbitMq("rabbitmq1", massTransitConfiguration: x =>
{
    x.AddConsumer<TestConsumer>();
});
builder.AddMassTransitRabbitMq<ISecondBus>("rabbitmq2", massTransitConfiguration: x =>
{
    x.AddConsumer<TestConsumerTwo>();
});
