Have you set you project to target .NET Framework 4.6.2 or later?

If so, and you still have the issue, please provide a small sample project which demonstrates the problem.

I recently updated my application to the QuickOPC 2018.3 but now whenever I try to run the application, it throws the following exception:
type 'OpcLabs.EasyOpc.AlarmsAndEvents.EasyAEClient' in assembly 'OpcLabs.EasyOpcClassic, Version=, Culture=neutral, PublicKeyToken=6faddca41dacb409' has method 'OnDeserializedMethod' with an incorrect signature for the serialization attribute that it is decorated with.
