The "You do not have IntelliSense configured" prompt no longer appears

[sean-mcmanus]

It used to appear when a user selects the “Do not configure with a compiler (not recommended) option and maybe some other cases.

It looks like it was incorrectly moved in PR https://github.com/microsoft/vscode-cpptools/pull/11427 .

I didn't find this bug -- it was reported by another "internal team".
