Onvif.Core's UdpClientWrapper calls IPGlobalProperties.GetActiveTcpListeners() in its ctor — unimplemented on mobile, so discovery threw Arg_PlatformNotSupported before sending a probe. - add PlatformSafeUdpClient (IUdpClient) that skips that pre-check, binds an ephemeral UDP socket and sends the multicast probe; replies are unicast so no multicast-group join / Android MulticastLock is needed - WsDiscoveryService uses it instead of UdpClientWrapper
