Backport of #10892 to vs17.12
Work item (Internal use):
Summary
Respect warning-as-error settings configured per-project when
-warnaserror
is passed on the command line.Customer Impact
Suppressing warnings is unnecessarily complicated and fails for confusing reasons.
Regression?
No, this behavior is longstanding, but the severity is higher with NuGet Audit because NuGet advises configuring warning-as-warning for audit warning codes.
Testing
Automated and targeted scenario tests.
Risk
Low: makes an existing opt-in codepath default.
