Windows ARM64 wheel support #1592
Description
PyPI currently does not appear to provide win_arm64 wheels for temporalio package.
Is Windows ARM64 intentionally unsupported, or has support simply not
been added to the release pipeline yet?
Would a PR enabling win_arm64 wheel publication be accepted?
Thanks.

Just an update that I was not able to build a whl locally and got hit by some build failures.

We don't have official windows arm64 support. If there are some changes we can make to support your local build, we wouldn't mind accepting those if they don't have major implications.

@omjavaid We have linux arm64 support now so we'd take a PR adding the same for Windows if you're inclined (following the similar validation we've done with linux)

Hi @Sushisource is this work planned? We have a WoA project here khmyznikov/PyEnv-WoA-State#1 and I could also take the work. Thanks

We don't have any plan to do this work. It would be ideal for there to be an actual user rather than publishing a new wheel just to check a box on a list.

Good point! I checked stats https://pypistats.org/packages/temporalio on average there are 4k daily downloads. Not sure the arm windows portion of it, but given more windows arm machine are released, there should be some of them.
I think one thing to mention is that give arm machine supports x64 python via emulation, so if arm python failed, user may switch to use x64 python directly instead of creating an issue here.
So it is worth considering if the effort is low as there could be users are silently blocked

It sounds like users would not be silently blocked. There would be a perf hit instead from emulation. If there is a user need for it we're happy to accept support, but that isn't very clear.
