(Actually I don't think that's even completely right for interfaces. Visibility and constructors/destructors aren't relevant there, but inheritance and static methods are...)
Eh, I was wrong about this part. Inheritance surprisingly doesn't matter, and static methods on interfaces are a C# version 8 feature.
