how does .net core implement dependency injection for different lifetimes?
how does a instance created and disposed for different lifetimes?

What I have tried:

What i could think is
1.singleton - use a global static dictionary to keep all the instance
2.scope - no idea.
3.transient - new instance() for every request.

how does .net core(or any other IoC library) do in the dependency injection engine?

You can have a look at the source code of a IoC container and find out for yourself. Here are the sources for Unity container[^] for example.

There are a series of articles here on CodeProject that answer this question. The first part can be found here: Dependency Inversion Principle, IoC Container, and Dependency Injection: Part 1[^] Most IoC containers provide similar implementations.
