Sometimes it works great, but usually after i started application (after log)- nothing happen. Just after i press key- consumers start to work (that's not displaying problem, because there are messages in queues and they are not going to be free before i press keyboard key).
At this demonstration i started current service. It took some messages and went to sleep. After that i sent more messages (using Web API application), but nothing happen in service. Just after i pressed key in service console window it woke up.
