ROSLYN.USAGE.CA2201 : Do not raise reserved exception types (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.USAGE.CA2201 : Do not raise reserved exception types (C#)

Summary

An exception of type that is not sufficiently specific or reserved by the runtime should never be raised by user code. This makes the original error difficult to detect and debug. If this exception instance might be thrown, use a different exception type.

This check corresponds to Roslyn rule CA2201. For full rule details, see the Microsoft website: CA2201.
