Logical endpoint

A logical endpoint is one that uses NServiceBus to process messages - each endpoint has an input queue which contains messages for the endpoint to process. A logical endpoint can contain multiple handlers or sagas. Each logical endpoint is uniquely identified by a name and can be deployed multiple times (and with multiple queues) for purposes of availability, scalability, or tenant/client separation.


A message is the unit of communication for NServiceBus. For licensing purposes only messages defined by users counts towards usage.
