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.PERFORMANCE.CA1872 : Prefer 'Convert.ToHexString' and 'Convert.ToHexStringLower' over call chains based on 'BitConverter.ToString' (C#)

Summary

Use 'Convert.ToHexString' or 'Convert.ToHexStringLower' when encoding bytes to a hexadecimal string representation. These methods are more efficient and allocation-friendly than using 'BitConverter.ToString' in combination with 'String.Replace' to replace dashes and 'String.ToLower'.

This check corresponds to Roslyn rule CA1872. For full rule details, see the Microsoft website: CA1872.
