"Dependency injection" (DI) seems like one of those hot buzzwords that will solve all your problems. But what is DI really? How does it help keep code clean and maintainable? And how do you take a legacy codebase and rewrite it to take advantage of DI? This talk takes an application written without DI and walks through the steps for "injecting" DI into the code. Learn the difference between "dependency injection" and "dependency injection containers". See how DI makes things like event-driven architectures simple to implement. And learn how DI leads to code that is easier to debug and test.
