Cleartext plugin in MySQL Connector/NET (no replies)

Hello,
Do you know how to use the Cleartext plugin with MySQL Connector/Net?
The MySQL Workbench has an advanced option to switch on the Cleartext plugin,
for example in case of SSL connection. It works fine with my MariaDB.
But unfortunately my C# client application fires the following error:
"Authentication method 'mysql_clear_password' not supported by any of the available plugins."
Any help is appreciated!
Regards,
Tibor
