C++/WinRT and the Future of C++ on Windows
summary
C++/WinRT is a standard, header-only C++ projection that replaces C++/CX and compiler extensions, delivered by a tool called cppwinrt.exe that turns WinMD inputs into consumable headers and optional component scaffolding. The demos show generating a projection from local WinMDs in a few hundred milliseconds and producing hundreds of namespace headers (demo listed ~280 top-level headers, overall projection ~1,032 headers), building a component, and running it with clang while preserving PDBs. Implementation uses C++17: constexpr metaprogramming, std::destroy, std::optional, string_view and coroutines; modules are proposed to eliminate 40+MB header compile pain.
