QuickOPC version 2018.1 (released today) has support for OPC UA Complex Data, and it can decode and encode the extension objects automatically.

I tried to write an ExtensionObject, and this appears to be possible! What I did is reading an ExtensionObject with the desired structure of the Node to write. Then I changed the bytes in the "Body" property and wrote it to the desired Node.
Next to that I will try to construct such an ExtensionObject from scratch in C# and send it. I'll keep you posted.

You did understand my question correctly. I will try it and let you know if this works out.

I am not sure if I understand your question. Do you have a need to Write the same or similar structures to the OPC server, so are you planning to construct Opc.Ua.ExtensionObject-s for that?
If so, and you then pass the extension object(s) to QuickOPC EasyUAClient.WriteXXXX method, things *may* work but we have never tested that. If you run into issues, let me know.

I downloaded the latest installer, because I was using 5.40 which does not include the assemblies. Now I am able to use the ExtensionObject!
I assume I can also use the Opc.Ua.Core to write to the opc structures?

It is actually alongside other assemblies (Assemblies\net452), but only if "Embedded Assemblies" is selected during install. If you use the one that we ship, it will be the right matching version.
You may also be interested in knowing that you actually need these assemblies only during build time, and not in run time. Copies of them are inside OpcLabs.EasyOpcUA assembly and will be used during run-time automatically, if not found on disk.

ps. In which folder should I find the Opc.Ua.Core library in case I want to use it?

This is what I was looking for. Yesterday I already tried to typecast with Opc.Ua.ExtensionObject from the Opc.Ua Stack from github.com/OPCFoundation/UA-.NET, but the build type is older then the one used in Quick OPC. I didn't know that you provided the stack as well.
What I did, on your advice, is using reflection. I figured out that I needed runtime reflection, so TypeDescriptor.GetProperties() from the System.ComponentModel. Indeed I can find the "Body" property now.
Thanks for now!
