Notes to Callers
As explained in Best Practices for Using Strings, we recommend that you avoid calling character-casing and string-casing methods that substitute default values. Instead, you should call methods that require parameters to be explicitly specified. To convert a character to lowercase by using the casing conventions of the current culture, call the ToLower(Char, CultureInfo) method overload with a value of CurrentCulture for its culture
parameter.
