MassTransit and RabbitMQ routing to tenant-specific consumers on .NET

There are 3 projects.

1. Core - shared classes.
2. Sender - A simple project which sends the message.
3. Consumer - A consumer project that accepts the message for a tenant defined in configuration.

Try it

1. Setup your RabbitMQ with default settings

Default is set in the Sender and Consumer projects, but you can change them to your needs:

configurator.Host("localhost",
    5672,
    "/", h =>
    {
       h.Username("guest");
       h.Password("guest");
    });

2. Configure and Run a consumer

Open the appsettings.json in the consumer and populate the tenantID you want to use for the consumer. For example:

{
...
    "TenantId": "f49fc7a9-155a-4d84-86bd-8276431524e1",
...
}

Now you can run the consumer, which will generate the RabbitMQ infrastructure and start listening for the messages.

3. Run Sender and send a message

Run Sender service and go to the /swagger and execute the sender endpoint. The below action will be triggered. Use the tenantId you specified in the step 2 above.

[HttpGet]
public async Task Send(string tenantId)
{
   await _sender.Publish(new MyMessage()
    {
        ID = "23423",
        Name = "My message",
        TenantId = tenantId
    });

   Ok();
}

Now you can try to run the second consumer with a different tenantID and try to send messages to both :).
