  • Hi Steven, I reinstalled 12  version & its working now. After I added a application & try to enable the extension then I got the error.

    UnknownException: An error occurred while detecting plugins in assembly 'Telligent.RewardPoint.Widget.Extension.dll'. (An error occurred while initializing plugins. Details of the issue were logged for review by the administrator.) ---> System.TypeLoadException: Could not load type 'Telligent.Evolution.Extensibility.UI.Version1.ICustomNavigationItem' from assembly 'Telligent.Evolution.Platform, Version=12.0.2.17146, Culture=neutral, PublicKeyToken=null'.

  • Telligent.Evolution.Extensibility.UI.Version1.ICustomNavigationItem was deprecated and removed.  Version2 has been deprecated as well in 12.x, use of Version3 is recommended for 12.x and later.  You will need to update your extension to use the new interface to be compatible with 12.x
