Code Inspection: String.CompareTo is culture-specific
Similarly to the Specify a culture in string conversion explicitly, this inspection helps to avoid problems with running your code on machines with different culture settings.
When strings are compared using
String.CompareTo, comparison results may differ depending on the machine's locale. The canonical example is the Turkish where there is a lowercase dotless "ı" with the corresponding uppercase "I", and a lowercase "i" with an uppercase "İ" with the dot. As a result, the method below may return different results on machines with different culture settings.
To resolve this problem, ReSharper suggests adding the culture-invariant
StringComparison.Ordinal explicitly to the method call.
