After reading your code and post, I am still not 100% sure what you are after. “Dependency injection” is just a tool, and tools are used to achieve goals. What’s your goal?
If you want to have a discrete set of implementors of a certain behaviour / protocol (the Elixir meanings of them) and then look them up / use them wherever the behaviour / protocol is needed then that can be done fairly easily and we can help you get there.
You do need to show an open mind however; insisting that Elixir must have what C# has is… not an interesting discussion. Elixir has the tools to achieve similar goals.
