Re: Are Application Services = Controllers

Oh, seems that I have mixed command handlers with controllers :)

So you have a REST Controller (presentation layer) which only dispatches to
multiple command handlers = application services (application layer).

Then the main difference is that Controllers are part of some presentation
layer while application services are from the application layer so the
application services doesn't know about controllers and the controllers are
(re)using application services ... and you of course must not put
application service code into the controllers..
