Dependency Injection On-Ramp

Dependency injection concepts and patterns in .NET help you start writing code that is easy to change and test.

What is Dependency Injection? The answers to the question seem to cause more confusion than help. This course will get us started on the road to understanding. We'll take an example-based approach to see the problems caused by tightly-coupled code. We'll add Dependency Injection to trade that tight-coupling for loose-coupling. And that loose-coupling makes our applications much easier to extend, maintain, and test. Finally, we'll see how Dependency Injection Containers can provide benefits that would be difficult to implement ourselves. This just scratches the surface. Once we're done, we'll be ready to start our journey on the Dependency Injection superhighway.
