 - Detect `ContainerInterface::get()` result type. Works better if you [configure](#configuration) compiled container XML file.
 - Detect return type of console arguments (`InputInterface::getArgument()`) and options (`InputInterface::getOption()`). Enforces
 to use InputArgument and InputOption constants as a part of best practise.
+- Detects correct Doctrine repository class if entities are configured with annotations. 
 - Fixes `PossiblyInvalidArgument` for `Symfony\Component\HttpFoundation\Request::getContent`.
 The plugin calculates real return type by checking the given argument and marks return type as either string or resource.
 - Detect return type of `Symfony\Component\HttpFoundation\HeaderBag::get` (by checking third argument for < Symfony 4.4)

+Multiple container files can be configured. In this case, first valid file is taken into account.
+If none of the given files is valid, configuration exception is thrown.
