Keep this in draft until actions/setup-python#931 has been confirmed resolved

[remyroy]

I think we might have to bootstrap installing Microsoft C++ Build Tools ourselves on that Windows ARM runner image or use custom images both of which are likely to add some complexity.

[yorickdowne]

I'm not convinced we should do this ourselves. We don't have to on Windows amd64 or any other image. I expect images to be ready for pip install wheel after setup-python. Let's see what Github has to say, surely they can fix this in either the image or the action.

Opened actions/partner-runner-images#19 for it

[yorickdowne]

A new Windows arm64 image is being built, which will include the dev tools. Give it a week or two.

[yorickdowne]

Pinged the arm team on this. “Soon” in August was clearly optimistic.

Latest was that building this image is quite challenging. After working through several issues, they have a new issue and escalated to the Azure team.

We can keep this open until there’s a working Windows arm64 image. Before Pectra? :harold
