Correct, that message will appear with newer versions of Python, because newer versions of Python are detected as 0.0 “unknown”, and 0.0 < 2.5. I mentioned a workaround in #6049 for this.

3.8 version cannot be detected properly by VS 2017, the only way to use that one would be to add a custom environment via the Python environments tool window and set the version manually to 3.6.

I would have expected 3.7 to be detected correctly, if it’s the standard Python 3.7 from python.org. You could try to add it as a custom env as well and see if that helps.

VS 2017 officially only supports up to Python 3.6.
