Depth Consulting - Calgary .NET User Group - Apr 22 2015 - Dependency Injection

This document summarizes a presentation on dependency injection. It begins with an introduction to dependency injection, describing it as providing objects their dependencies rather than having them construct dependencies themselves. It then discusses the different ways dependencies can be injected through constructor or property injection. It also covers the different types of dependencies that can be injected, such as interfaces or concrete classes. The presentation demonstrates dependency injection with a code example and discusses how dependency injection containers can help manage object lifecycles and make development easier. It acknowledges some challenges with dependency injection but emphasizes that it leads to better design, testability and code quality.
