Aha, that almost makes sense. You're saying "add 2" might mean a component that exposes two methods. Not sure what exactly he is demonstrating there, actually.

Aha, that almost makes sense. You're saying "add 2" might mean a component that exposes two methods. Not sure what exactly he is demonstrating there, actually. I mean, here's a DLL written in C that exposes the same two methods (although not asynchronous): int Add(int a, int b) { return a + b; } int Sub(int a, int b) { return a - CountEveryBitByHand(b); } So, I guess the example is just to show the async stuff, really.
