publishAsync immediately returns when awaited

I think you are looking for more of a request / response messaging pattern. We don't currently support that. When you publish the message it's sent out to all subscribers. It's a pub/sub model.

Indeed that's what the code is expecting, though being familiar with the pub/sub model, the actual behaviour is exactly what I would have expected (the code was not written by me). However, looking at the code for the in-memory implementation it looks like everything is awaited all the way down, so I'm still wondering why is this not resuming execution only after all subscribers have run? As mentioned, I wrote a simple console app where the subscriber had a delay of a few seconds, and saw that being correctly recorded by the stopwatch. Do you care to elaborate a bit?

PublishAsync is only publishing the messages which normally would mean sending that message to some sort of messaging server. The message handlers are then run separately. So even with the in memory implementation, the handlers are called separately from the publish.

Makes total sense, just wanted to check whether I was missing something. Thanks for clarifying!
