Azure service bus and masstransit, same message, different namespace

Question

i'm using Azure service bus with masstransit it works perfectly if the message class type is inherited from the same project, but once the message is sent from another .net projet , so different namespace in "messageType" property, it goes automatically to deadletter and my consumer is unable to catch it, what is the solution in this case ? because I cannot oblige different publishers (differents teams) to put the same namespace for that message type class thank you
