Add ARM64 Windows environment

Feature: Add Windows ARM64 as an environment

Hi there, are there any plans to support a hosted ARM64 environment? We're seeing quite some enthusiasm over here: microsoft/vscode#33620

Hi @joaomoreno, unfortunately not at this time. Adding extra environments currently affects overall capacity and how we can serve the existing environments. If that changes in the future we'll definitely consider it. Have you looked into setting up your own self-hosted runner?

@alepauly Windows ARM64 doesn't seem to be a supported platform for self-hosted runners, or am I missing something?

Hi @joaomoreno, you aren't missing anything, my bad. I wasn't looking at the Windows part of your request and was thinking the runner could run on ARM64 but that's not true on Windows. Until DotNet Core doesn't run there, we probably won't be able to support it.

Just for the record, I just created a PR to add support for Windows ARM64 to GitHub Actions runners (self-hosted): actions/runner#785
