All the new elements are gone and have been replaced by simple dependency registration (singleton lifetimes, in this case). These little differences give us the tools to reimplement any part of the subsystem if we want to, as we cover soon.
We can register bindings in the transparent façade extension method because classes and interfaces are public. The container needs a public constructor to do its work.
In the opaque façade, we had to define the constructor of the OpaqueFacade class as internal because the type of its parameters (ComponentA, ComponentB, and ComponentC) are internal, making it impossible to leverage the container. Changing the visibility modifier of the opaque façade constructor from internal to public would have yielded a CS0051 Inconsistent accessibility error.
