Does anyone know a C# OPC client sample application? I'm looking for a good opensource one to learn about the protocol. I would prefer it if it uses OPC foundation .net core apis.

There is a .NET project named 'My OPC Client' here: http://hadiscada.blogspot.com/2013/07/my-opc-client.html it coded with VB but I think it can be converted to C.
