Okay, so I'm porting my game to Windows Metro, because I believe it will be pretty well suited for it due to it's mechanics and minimalist art style. And of course, I'd like to target Windows 10 and take advantage of some of it's exclusive features, such as Cortana. Now, I've never actually used any APIs for Cortana before and I'm still rather new to writing apps for Windows Metro, but I think it would be a rather nifty feature to use in my game. So far, every example I find is for Windows Phone 8, which is great in all because I'm supporting that too, but nothing in C++ so far. Every example uses C#, and that's not the language my game uses.
So my question is (for those of you who are actively dev'ing with the Windows 10 preview), are the APIs basically the same between Windows Phone 8 and Windows 10? And where can I find the APIs for C++? All I can find is C# so far.
