I\'m pondering the design of a C# library, that will have several different high level functions. Of course, those high-level functions will be implemented using the SOLID c
What I would do is design my library in a DI container agnostic way to limit the dependency on the container as much as possible. This allows to swap out on DI container for another if need be.
Then expose the layer above the DI logic to the users of the library so that they can use whatever framework you chose through your interface. This way they can still use DI functionality that you exposed and they are free to use any other framework for their own purposes.
Allowing the users of the library to plug their own DI framework seems a bit wrong to me as it dramatically increases amount of maintenance. This also then becomes more of a plugin environment than straight DI.
