hoping it’s a simple question with a clear answer : what layer should mass transit be, one thing to note it’s used as background service for now, that could be changed in the future who knows, the app is not that complex, no microservices are involved (yet), so am just curious at what layer should it be and why.

am thinking application layer, for this simple case that makes sense that message publisher and consumers should be in application layer, but am not sure in case later on it turns more complex that and involves azure service bus, i feel like maybe it should be at infra layer ? just want to hear reasoning as to why or why not it shouldn’t be in application layer.
