If you are serious about cross-platform, the answer is simple, and has been the same for decades: don't use Visual Studio to build for Windows, as it isn't offering you anything of value. This answer used to be maybe a bit controversial--hell: I even supported Visual Studio for years back in the early '00s--but now even Chrome builds with clang... if it is good enough for Chrome, it is good enough for you.
the main soft I develop (https://ossia.io) has been built through clang/libc++ on msw for 4+ years now so you are preaching to the choir, but many companies insist in building with msvc and you cannot just tell them "no"
