Windows support for OCaml is often seen as lacking compared to Tier-1 platforms like Linux and macOS. The goal of the first-class Windows project is to provide an OCaml development and user experience on Windows that matches the quality found on Linux and macOS. Ultimately, we expect that First-class Windows will significantly enhance OCaml adoption by making OCaml accessible to a broader audience and easing the onboarding process for new users. It will also expand the use of tools written in OCaml, such as Coq and Flow. This is ongoing work. In this presentation, we describe the toolkit we have put together to make Windows a first-class citizen for OCaml.
