What's wrong here?

p.s. i've used the reloa the XML instead of building all the time the configuration in code: UaPubSubConfigurationHelper
Anyway also when building in code didn't work

Expected Behavior

I expect that the subscriber application receive the data published by the publishing application.

Steps To Reproduce

I've used the Quick Start for pub sub and just reduced to the Simple dataset only.

Environment

- OS: macOs
- Environment: vscode
- Runtime: .net7
- Nuget Version:   
<ItemGroup>
    <PackageReference Include="OPCFoundation.NetStandard.Opc.Ua.Core" Version="1.5.372.1-rc" />
    <PackageReference Include="OPCFoundation.NetStandard.Opc.Ua.PubSub" Version="1.5.372.1-beta" />
  </ItemGroup>

- Component: Opc.Ua.Core.PubSub
- Server:
- Client:

Anything else?

Ok at least i managed to get Logs

11/04/2023 10:44:58.474 NetworkInterface name('en7') attempts to create instance of UdpClient.
11/04/2023 10:44:58.474 UdpClientMulticast was created for local Address: 192.168.1.195:4840 and multicast address: 224.0.2.14.
11/04/2023 10:44:58.475 Cannot use Network interface 'en7'. Exception: Socket.IOControl handles Windows-specific control codes and is not supported on this platform.

But with the XML i posted i didn't configured an unicast address? why it still trying to use multicast?

And, is that library unsupported on MAC?

Ok, i've configured the Discovery endpoint as it seems it was using Multicast, anyway even in unicast i'm getting the "Socket.IOControl handles Windows-specific control codes and is not supported on this platform." error.

Unfortunately it's not clear what's the specific code rising this exception.

Anyone else having such issue on a mac?

BTW tried also on Windows, i'm not getting anymore the "Windows Specific" issue of course but still wasn't able to have the sample running using unicast.

Converting to discussion. Feel free to change to an issue if any defect for the .net stack is identified during the discussion.

Ok, how this conversation will work? Is there anyone who may help me on configuring this library to work on OPC UA PubSub over UDP?

Hello, did you get it running ? I am currently struggling with the same thing. I did configure and run the publisher but nothing is flowing on wireshark unfortunately.
