PR Summary

This is a regression from a prior change that replaced usage of `n with $newline but accidentally replaced a correct usage of `n as the PositionMessage member uses `n as the newline is from a resource string. Fix is to change back usage of Split() with the newline char rather than $newline which may contain CRLF. This is a regression introduced in rc.3 from rc.2

PR Context

The error message was inadvertently including the legacy line position information.
