ROSLYN.SECURITY.CA5394 : Do not use insecure randomness (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.SECURITY.CA5394 : Do not use insecure randomness (C#)

Summary

Using a cryptographically weak pseudo-random number generator may allow an attacker to predict what security-sensitive value will be generated. Use a cryptographically strong random number generator if an unpredictable value is required, or ensure that weak pseudo-random numbers aren't used in a security-sensitive manner.

This check corresponds to Roslyn rule CA5394. For full rule details, see the Microsoft website: CA5394.
