(I didn't check the RFC; I'm going by memory here.) That would include interface properties by nature. > > --Larry Garfield Using property accessors on interfaces is fine too, but the one thing that properties directly being defined on interfaces do bring is that you don't have to repeat implementation of those in your implementations. That's a detail, but a practical one. Regards, -- Pierre
