Description
The CultureInfo class contains information about a specific culture, i.e. the locale. This information is potentially used during sorting, formatting datetime, comparisons, and other related operations. Although methods like ToLower and ToUpper do not mandate that you provide this information, it is recommended that you do so, to avoid pitfalls.
Bad Practice
var lowerCase = str.ToLower();
Recommended
var lowerCase = str.ToLower(new CultureInfo("en-US", false));
