Congratulations on the launch, and for your support of open source projects! I'm interested in extending our bulk builds of the OCaml language community packages (https://opam.ocaml.org) to Windows. Do Azure Pipelines support Windows Docker containers yet? Having somewhere to robustly build native Windows images is quite difficult at the moment.

One of the other things on my wishlist is for some sort of standard for all these CI/CD pipeline agents. So far, on our build cluster we have BuildKite, GitLab, Azure Pipelines, <insert CI provider> agents, each of which have slightly different platform support. It's particularly challenging when trying to extend our CI to slightly less popular operating systems such as OpenBSD or exotic or newer architectures such as ppc64le or RISC-V. It wasn't clear from the Azure documentation whether or not the agent is open source or not.

Today, we use a combination of BuildKite and GitLab to coordinate the multi-OS, multi-CPU-arch Docker images that then get pushed to the Hub. The first provider to give us a one-stop coordinated multiarch build pipeline will save open source projects like OCaml so much trouble for testing and publishing our releases!
