Sorry I forgot about this.
So I learned that Supports() returns the correct interface (IHook in my
example) and THAT I can see is helpful now because the implementation of the
interface can be shared across many classes. That’s what I was looking for in
terms of a practical use patterns for “implements properties”. I should have
seen that at the start but I’m still hung up on how it’s implemented.
