I am followed all steps but I put the annotation on method. I get this error:

FileLoaderImportCircularReferenceException in FileLoader.php line 97:
Circular reference detected in "C:\htdocs\pronaturalis\app/config/routing_dev.yml" ("C:\htdocs\pronaturalis\app/config/routing_dev.yml" > "C:\htdocs\pronaturalis\app/config\routing.yml" > "C:\htdocs\pronaturalis\src\MLM\Bundle\MLMBundle/Controller/" > "C:\htdocs\pronaturalis\app/config/routing_dev.yml").

Any idea what could be wrong? I am using Symfony 2.6

@dextervip I had the same error when I tried to create a service that provide me the annotation reader object to pass as an argument in the annotation driver service (all this because the service; @annotation_reader its not reconized) I solve this creating a class (AnnotationReaderSon) that extends Annotation Reader (from Doctrine Common), and then creating a service from the new class 'AnnotationReaderSon'.
