Code inspection: The CallerMemberNameAttribute will have no effect; it is overridden by the CallerLineNumberAttribute

This inspection reports a parameter marked with both [CallerMemberName] and [CallerLineNumber]. [CallerLineNumber] overrides [CallerMemberName] on the same parameter, so the member name attribute has no effect and only makes the code misleading.

Example

                using System.Runtime.CompilerServices;
                void Log([CallerMemberName, CallerLineNumber] object info = null)
                {
                }
            

                using System.Runtime.CompilerServices;
                void Log([CallerLineNumber] object info = null)
                {
                }
            

How to fix

There is no dedicated quick-fix. The usual fix is to remove the overridden attribute.
