I need to connect to an existing queue in a RabbitMQ instance where I don't have permission to create exchanges. My goal is to consume messages from this queue, not to produce or publish them.

For example, the queue "demo-queue" already exists and is bound to an existing exchange "demo-existing-exchange," where messages are published by another producer.

I'm have to configure the consumer using the ConsumerDefinition class. Here is my current code:

public class DemoConsumerDefinition : ConsumerDefinition<DemoConsumer>
{
    public DemoConsumerDefinition()
    {
        Endpoint(x =>
        {
            x.Name = "demo-queue";
            x.ConfigureConsumeTopology = false;
        });
    }
}

In my testing environment, where I have full permissions, I manually created both the "demo-queue" and "demo-existing-exchange," and I bound the queue to the exchange. When I run the application, it correctly consumes messages from the queue, but MassTransit still creates a new exchange named "demo-queue."

I want to prevent this because, in the production RabbitMQ instance, I won't have permission to create exchanges.

Is there a way to stop this exchange from being created?
