Description

I wanted to add the possibility to translate Microsoft DI abstracted packages into Reflex. The main blockage I found was when I couldn't translate the factory bindings from Microsoft DI to Reflex. This can be easily allowed by just implementing IServiceCollection in the Container, and allowing for Func<Container, object> factory binding to exist. I wanted to know also if adding the Microsoft.Extensions.DependencyInjection.Abstractions .dll goes against the guidelines of the project.
I was just trying to make a simple bridge for IServiceCollections that loads the bindings into Reflex Containers.
