nservicebus unsubscribing when we want it to subscribe

Question

We have an NServiceBus 3.0 publisher running under the production profile.

When a subscriber starts up it sends the subscription messages to the publisher but the publisher does not add them to Raven. Infact in the publisher's log is the entry:

NServiceBus.Unicast.UnicastBus [(null)] <(null)> - Unsubscribing subscriber@servername from message type MyMessage, MyMessages, Version=1.0.20323.2, Culture=neutral, PublicKeyToken=XXXXXXXX

When the bus does a Publish() the subscriber does not receive a message because it would seem as if the publisher cannot process the subscriptions.

Any help would be stellar as we have a demo tomorrow.

Answer 1

Make sure that all your endpoints are 3.0.1. 300 is not compatible with 301 without the nsb.compatibility.dll in the bin dir
