ci: remove Windows Server 2016 from builds on Azure Pipelines #652
Conversation
The images with Windows Server 2016 / Visual Studio 2017 have been deprecated by Microsoft and are in the process of being removed completely, so that no further builds with that image will be possible. For reference, see * <https://devblogs.microsoft.com/devops/hosted-pipelines-image-deprecation/> * <actions/runner-images#5238> Since it seems that Microsoft is basically using the same build environments on both Azure and GitHub Actions when it comes to Windows and Visual Studio, I decided to remove those jobs instead of updating them to a newer version of the image. The tests that would be possible with newer images on Azure are basically what we are already doing with GitHub Actions.

IMPORTANT NOTE FOR THOSE OF YOU STILL STRUGGLING WITH WIN2016 BROWNOUT NOTICE. CHECK EVERYTHING! NOT JUST YOUR PIPELINE CODE, CHECK PIPELINE TRIGGERS POOLS. CHECK RELEASES POOLS, CHECK ALL THE POOLS EVERYWHERE ON YOUR DEVOPS ACCOUNT. WHAT WILL HAPPEN IS YOU WILL EVENTUALLY FIND SOMETHING STILL SET TO USE WIN2016 POOL. ONCE YOU FIND ALL OF THEM YOUR ACCOUNT WILL NO LONGER GET THE BROWNOUT NOTICE EVEN DURING THE SCHEDULED TIMES. SO IF YOU ARE GETTING THE NOTICE ITS NOT YOUR WIN2017 POOL, OR WIN-LATEST IN THE YML, ITS SOMETHING ELSE, AZURE NOTICES ARE DOING A TERRIBLE JOB ON THIS WITH THEIR WORDING AND WHERE THE NOTICE APPEARS. THE NOTICE MEANS YOUR AZURE DEVOPS ACCOUNT IS STILL USING WINDWOS POOL SOMEWHERE, YOU DID NOT CHECK EVEYWHERE. |

AFAICT, nothing uses Win 2016 pools anywhere under |

I've just encountered the problem in #651
where the VS 2017 / Windows 2016 builds refused to start:

Since it seems that Microsoft is basically using the same build
environments on both Azure and GitHub Actions when it comes to
Windows and Visual Studio, I decided to remove those jobs instead
of updating them to a newer version of the image. The tests that
would be possible with newer images on Azure are basically what
we are already doing with GitHub Actions here.
Looks like the new final deadline for removal of Windows 2016 is
30th June 2022. But until that happens there will be several
"brownouts" lasting 24 hours each where users will see error
messages that indicate the image will be removed soon. This
basically means we cannot rely on Windows 2016 anymore, even
before 30th June.
