I’ve noticed issues with SecureString when the string or password exceeds 16 characters. It works fine as long as the application remains open, but upon restarting, I only retrieve the first 16 characters instead of the full string.
Example:
This limitation affects Instruments and ComponentsSettings. I assume it impacts TestSteps in the same way.
It likely happens during XML serialization?!
Could this limitation please be removed?
