I see no reason to point to anything but the newest Visual Studio, and any of the v14x toolsets (there are no v15x toolsets to worry about yet, so this is essentially the newest MSVC).
Ideally, I'd rather Python _users_ point package developers to this page so they can release wheels, rather than expecting users to manage package compilation. But if they've ended up with that job then Visual Studio is still the safest recommendation. The Build Tools are only slightly more convenient, but they also obscure the license terms users are working under because they implicitly require the acceptance (and eligibility) of a Visual Studio license. So for simplicity: install latest Visual Studio, with Python workload and Python Native Development option. For specificity: install any v14x MSVC toolset for your target platform(s), and the latest Windows SDK (which are all found in the VS installer under Native development). Set $env:PlatformToolset to your toolset version before building if it doesn't detect it. Currently we're using the v143 toolset for releases, but this can change at any time because it has no impact on the ABI. If someone wants to put that information on the page, feel free, but I'm not volunteering to keep it updated :) The "official" source of truth is https://github.com/python/cpython/blob/main/PCbuild/python.props Cheers, Steve (Apologies for the messed up quotes below, I can't override my work email's settings on this.

Would it be a good idea to point Python users in the same direction or is there a less involved setup/download available ?
