ROSLYN.DESIGN.CA1062 : Validate arguments of public methods (C#)

JavaScript is not currently enabled, but is required for full CodeSonar manual search and browse functionality.

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.DESIGN.CA1062 : Validate arguments of public methods (C#)

Summary

An externally visible method dereferences one of its reference arguments without verifying whether that argument is 'null' ('Nothing' in Visual Basic). All reference arguments that are passed to externally visible methods should be checked against 'null'. If appropriate, throw an 'ArgumentNullException' when the argument is 'null'. If the method is designed to be called only by known assemblies, you should make the method internal.

This check corresponds to Roslyn rule CA1062. For full rule details, see the Microsoft website: CA1062.
