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.SECURITY.CA5361 : Do Not Disable SChannel Use of Strong Crypto (C#)

Summary

Starting with the .NET Framework 4.6, the System.Net.ServicePointManager and System.Net.Security.SslStream classes are recommended to use new protocols. The old ones have protocol weaknesses and are not supported. Setting Switch.System.Net.DontEnableSchUseStrongCrypto with true will use the old weak crypto check and opt out of the protocol migration.

This check corresponds to Roslyn rule CA5361. For full rule details, see the Microsoft website: CA5361.
