It would be fine with me if I could simply compile any valid C99 or even C11 code with Visual Studio C++ compiler, but C99 support is only half-assed, and C11 support probably will never happen.

D3D11's C API works fine (that's the only Windows API I care about apart from the usual Win32 windowing stuff), but already D3D12 let that rot and is only usable from C with workarounds (doesn't matter though since D3D12 is fairly niche).

All in all it's a shame though because the newer C features are much more sane and useful than anything in C++14 or C++17.

The name says it all, Visual Studio C++ compiler.

There is no written rule that C++ compilers are obliged to be C compilers as well.

Again, as C++ compiler, they are only required to be as compatible with C code as ANSI C++ requires.
