On Windows 7 I was using Microsoft Visual C++ as CCompilerDriver. For this, the minimal solution is to install Microsoft .Net and then Microsoft SDK-7.1. There is no need to install Microsoft Visual Studio.
Now I am trying to install Microsoft C++ compiler to work with Mathematica 11 on Windows 10. The difference with Windows 7 is that in Windows 10 Microsoft .Net is a part of OS. Another difference is that SDK-10 does not contain C compiler, as I have found after installation. And it is impossible to install SDK-7.1 as it seems to be incompatible with the pre-installed .Net.
Could anybody propose a minimal solution to install the Microsoft C compiler on Windows 10?
