Machines were updated to a newer VS 16.4 but CMake is 3.15.1 which is too old for VS validation of incremental native targets. We need 3.15.5 at least. All PRs and CI are failing on Windows to build Libraries because of this.
@stephentoub @buyaa-n @eiriktsarpalis this would impact nullable as they will be expressed as warnings on PRs. So we have to lookout for those before merging.
