Seeing this in Azure Pipelines now:
DEPRECATION: azure-devops is being installed using the legacy 'setup.py install' method, because it does not have a 'pyproject.toml' and the 'wheel' package is not installed. pip 23.1 will enforce this behaviour change. A possible replacement is to enable the '--use-pep517' option. Discussion can be found at pypa/pip#8559
I've suppressed this with the --use-pep517 option as mentioned above, but this is not ideal for new users.
