When you're installing Visual Studio the C++ tools version is listed under the selected components as "v14x".

However, at this stage, the *only* version in circulation is 14.x - mine shows v142. Until the 14 changes to a "15", it will be binary compatible and so you can use any version at all to build CPython and/or extension modules.

Our official releases are always using relatively up-to-date compilers, but provided the compatibility is maintained on Microsoft's side, there's no need to worry about the specific versions.

Cheers,
Steve

    Is it still correct to specifically use VS2017 , or is VS2019 also
    acceptable?

    We have to update the devguide. VS 2019 is supported, probably even
    recommended, as long as the C++ tools are v14.x.
