Not for 5.0, the aim of 5.0 was to focus on getting multicore support out of the door. Thus only mingw64 is supported for Windows. Support for MSVC will come with later versions. At the same time, improving opam ecosystem support for Windows is one of the major goal of opam 2.2 . Thus hopefully the support for native Windows will improve in the future (next year?).
