According to ms you should enable Windows SDK 10.0.20348.0 in VS installer. Problem is it is missing!
How do I enable C11 standard in Visual Studio 2019? It is not listed under C++ standards, I have there C14, C17 only.
I tried C11 code and it throwed error and I googled - it is because VS 19 doesn't fully support C11. And didn't find anything other which would be useful.
