The Dependency Injection Container and You

Drupal 8 extends the Symfony 2 dependency injection container. What is a dependency injection container anyway? What do I need to know? This is an overview of the patterns of dependency injection, factories, dependency injection containers, and Symfony 2 and Drupal 8's use of them.

Finally the session continues on with how a Drupal developer can leverage the dependency injection container and how & when to define your own services.

This is a developer-heavy "beginner" session that has been updated with the last year of development in Drupal 8.
