You know the basics of dependency injection (DI). Now it's time to take a closer look at how DI patterns and other design patterns can help us use DI effectively. We'll look at implementations and uses for DI patterns including constructor injection, method injection, and property injection. In addition, we'll use other design patterns to add functionality to existing objects and to manage disposable dependencies. We'll leave with several practical ways to improve the functionality and testing of our code.

Code samples and slides are included in this repository.
