Oh, there is no microsoft/windowsservercore:latest tag, MSFT has removed the latest tag long time ago. Maybe AppVeyor got it for convenience reasons. Should be ltsc2019 nowadays.

Hello @StefanScherer thank you for pointing that out. After playing lottery with the windows host, it turned out to be ltsc2016.

Now the process is dying on this line:
RUN powershell iex(iwr -useb https://chocolatey.org/install.ps1)

claiming it can't validate the SSL connection to chocolatey.org... (I have seen that in places where some protection software running on the host puts itself in the middle to do some sort policing
on endpoints. I actually have seen this particular problem with chocolatey.org).

I tried to add a -SkipCertificateCheck flag just to realize it is only supported in PowerShell 7. Of course ltsc2016 is running stock 5.0 (where the flag is not allowed).

Any ideas 🤔?

Oh, indeed ltsc2016. Well that can be fixed by updating the AppVeyor image.

In the appveyor.yml use Visual Studio 2019 which is installed on a Windows Server 2019. Docker has evolved a lot since Server 2016 came out, I encourage to use the newest OS available.

Hello @StefanScherer thank you for the tip! New to AppVeyor. It seems like it passed ok.
