You can find out what services are registered with the container using the console. To show all services (public and private) and their PHP classes, run:

$ php bin/console debug:container # add this option to display "hidden services" too (those whose ID starts with a dot) $ php bin/console debug:container --show-hidden
Hidden services and the
--show-hidden option were introduced in Symfony 4.1.
To see a list of all of the available types that can be used for autowiring, run:
$ php bin/console debug:autowiring
