Unfortunately the WCF binding does not allow this. The reason is that
each Service creates a new AMQP binding and a new queue for requests.
Therefore each Service will receive all requests, leading to the errors
you see.

An alternative is to create separate endpoints for each worker and to
round-robin at the request stage.
