I'm currently writing a cross-platform toolkit, and I'd like to know what native looks like in Windows. As far as I can tell it's worse than Linux. You have the old Win32 / MFC style widgets, and programs like Notepad++ that use something that looks similar. There's the style that much (but not all) of the Control Panel seems to use (is the name Metro?), but the only application that I've used that uses anything similar to that is the Edge browser. There's also the MS Office style, but that seems like a one-off, except that Explorer seems to use it. I've heard things about WFC, which seems to be deprecated, no idea what it looks like. I really dislike the Windows experience, so I have limited recent experience since I avoid using it as much as possible, but so far every application I've used looks different.

I'd like to know what the "native experience" is supposed to be, but I have no idea which of the numerous Microsoft UI APIs is officially current. So far I've just punted and I'm using macOS shapes and sizing and using the colors from the Metro? style; at least it will look tasteful and not stand out too much color-wise.
