COM has always supported C. Go and look at any headers generated by MIDL and you’ll see a C variant of the interfaces. I don’t see why you couldn’t write a UWP app in pure C, you’d just need a shitload of boilerplate and glue to make it sane to work with. Though the C++ projection contains quite a bit of boilerplate itself, so... shrug
