You need to use a RabbitMQ topic exchange.  It does not matter whether
you use the C# .NET client, or the full WCF integration, because both
perform the same *underlying* AMQP action of publishing to an
exchange.  It is the topic exchange and routing key that gives you the
pubsub behaviour you want.  See the user guide for more info.
