Socket AddMembership on RAW sockets not accepted in MF

It seems that the NETMF does not accept Multicast on RAW Sockets in contrast to the big .NET framework.

Anyone knows how to retrieve a remote endpoint. IP and port number on Dgram sockets, or to make a RAW socket accepting multicast? Maybe through IOCTL?

UPDATE: Found the solution for Dgram sockets

var buf = new byte[socket.Available];
EndPoint remoteEndpoint = new IPEndPoint(IPAddress.Any, 0);
socket.ReceiveFrom(buf,ref remoteEndpoint);

The endpoint is populated after the ReceiveFrom :-[
