A code-based registration vs a design time registration in the context of the IoC

Question

What is the difference between the code-based registration and a design time registration in the context of the IoC?

I met the concepts here while learning the IoC, DIP, DI and IoC containers.

Answer 1

After learning a little bit more about the IoC I come to a conclusion that the code-based registration is about registering the types with the help of an explicit code and the design time registration is about registering the types with the help of the C# attributes.
