If you are viewing this file in your hub's Web GUI, enable JavaScript in your browser: you will also need it for GUI functionality.

If you opened this file directly from disk, your browser may be directly suppressing JavaScript functionality: certain browsers perform this suppression on local files (but not files delivered by web servers) for security reasons.

If you access the manual through the hub's Web GUI, the functionality will not be suppressed because the hub is a web server.
Alternatively, your browser may allow you to explicitly disable the security setting that suppresses functionality. See the CodeSonar FAQ for more information.

ROSLYN.GLOBALIZATION.CA1310 : Specify StringComparison for correctness (C#)

Summary

A string comparison operation uses a method overload that does not set a StringComparison parameter, hence its behavior could vary based on the current user's locale settings. It is strongly recommended to use the overload with StringComparison parameter for correctness and clarity of intent. If the result will be displayed to the user, such as when sorting a list of items for display in a list box, specify 'StringComparison.CurrentCulture' or 'StringComparison.CurrentCultureIgnoreCase' as the 'StringComparison' parameter. If comparing case-insensitive identifiers, such as file paths, environment variables, or registry keys and values, specify 'StringComparison.OrdinalIgnoreCase'. Otherwise, if comparing case-sensitive identifiers, specify 'StringComparison.Ordinal'.

This check corresponds to Roslyn rule CA1310. For full rule details, see the Microsoft website: CA1310.
