Unable to connect to WebLogic JMS Server after upgrade to 12C using C# JMS Client

User_OSDOJ

Any assistance with below error is appreciated. I got this error after upgrading our current JMS Server from (WebLogic 10.3.2.0) to WebLogic 12.2.1.3.

I updated the WebLogic.Messaging.dll of the client(C# app) from 1.1.0 to 1. 3.4, however error still persist.
