}When , the CommandLineParser will use StringComparisonOrdinal for command line argument comparisons; otherwise, it will use StringComparisonInvariantCulture. Ordinal comparisons are not used for case-sensitive names so that lower and upper case arguments sort together in the usage help.
To use a different StringComparison value than the two mentioned here, use the ParseOptionsArgumentNameComparison property.
This value can be overridden by the ParseOptionsArgumentNameComparison property.
