Dependency Injection for Absolute Beginners with C# and .NET

Dependency Injection can be daunting at first. In this video I make an attempt to explain it to you as simple as possible. By flying in a couple of C# code snippets we learn how to turn a hard reference into a dependency that is injection. But why stop there? Let’s decouple our code more by adding interfaces in the mix.

Last but not least, you will see what constructor injection is and what a DI container is. Hungry for more? Let me know in the comments what you’d like to see!
