Read extended BaseEvent fields|OPC UA Implementation: Stacks, Tools, and Samples|Forum|OPC Foundation

Hello everyone,

I have this kind of structure regarding subscribed EventType:

(If you can't see the image click here https://ibb.co/549RSHG )

+BaseEventType

----EventId

----EventType

----Other standard EventType fields

++++MachineStatusEventType (This one extends the BaseEvent and has got some fields like CurrentStatus, SerialNumber...)

When I subscribe the event I get the event notifier callback, but with only the standard fields. 

How can I read the MachineStatusEventType fields?

I'm using .NET SDK, but if you have examples in JAVA/C++ I will "translate" in C# code.

Thanks in advance to all!
