--- Comment #9 from Anastasius Focht focht@gmx.net --- Hello Jan,
--- quote --- I just retested and it still fails. --- quote ---
Please always specify the exact Wine version you tested with. This also allows to deduce the Wine-Mono version (4.7-ish?).
Well, I don't have this specific hardware but I think the app should work with MS .NET Framework and proper raw sockets setup (setcap). Troubleshoot IGMP Multicast with Linux tools first to ensure the use-case is not a Linux host/network configuration issue.
Regards
