An explanation of dependency injection in C# by building a custom DI container with singleton and transient lifetimes.

In this dependency injection c# tutorial I answer the questions: what is dependency injection? how does dependency injection work? how do dependency injection lifetimes work? We implement our own dependency injection container and a resolver (which really could just be one object) with singleton and transient lifetimes for our dependencies. Primarily we are trying to understand that we want to know about all possible dependencies, so when we try to use a service we can assemble it automatically, and all services come from one source.

On “How does .net core dependency injection work”

There’s a really nice video from “raw coding” that goes through building a primitive DI container in .net (link below). It’s helpful for understanding what goes on behind the scenes even if it’s not exactly how Microsoft’s framework is implemented. The concepts aren’t too hard but DI containers are often bewildering because there’s a lot of stuff that occurs “by convention” and not easy to infer what’s happening unless you’ve been using these a lot. link to this video

On “ELI5 the idea of registering my services in dependency injections containers”

After watching this: link to this video all these things made sense for me. Highly recommend it.
