title: MassTransit pulling messages from external system
body: <p>How can MassTransit pull messages from a RabbitMQ when the messages were sent from a different message sending source(RabbitMQ Client in this case)?</p>
  
  <p>The messages share the same C# message contract and serialized as json.</p>
  
  <p>The current error I receive is masstransit parsing error... </p>
