ROSLYN.GLOBALIZATION.CA1309 : Use ordinal string comparison (C#)

See Roslyn-Detected C# Warning Classes for more information.

Summary

A string comparison operation that is nonlinguistic does not set the StringComparison parameter to either Ordinal or OrdinalIgnoreCase. By explicitly setting the parameter to either StringComparison.Ordinal or StringComparison.OrdinalIgnoreCase, your code often gains speed, becomes more correct, and becomes more reliable.

This check corresponds to Roslyn rule CA1309. For full rule details, see the Microsoft website: CA1309.
