In the past there were repeated issues with the cirrus install of visual
studio missing some things, and modifying the install to install them was very
slow, that's why I had switched to installing VS ourselves.
I suspect that the other issue right now is that they updated the host to
a newer version of windows, and when container and host version don't match,
the windows container stuff gets slower starting up.

Why is the build phase so slow in that image? 12min? That's way slower than
the windows builds normally.

I am strongly against that. For one, the amount of traffic that causes with
the software providers is substantial. For another, the failure rates of
downloading stuff every time are quite high.
I think pruning the container from unnecessary content, and trying to base it
on the vs 2022 image (which is prel-loaded onto the host) is a better plan.
