MS .NET VS C++ and Socket Class doing Raw IP ReceiveFrom

[ssherm01]

I'm using MS VS C++ .NET. I've written a multicast test utility that can
send IGMP packets for a user specified group address. As well, it can
send and receive UDP packets for a specified multicast group. I'm using
the Sockets Class methods for sending and receiving packets. One area I'm having problems with is recieving IGMP packets on the Raw IP socket.

Here is the main calls I am using to receive IGMP packets.

    s = new Socket(AddressFamily::InterNetwork, SocketType::Raw, 
                            ProtocolType::Igmp);
    s->SetSocketOption(SocketOptionLevel::IP, 
                                  SocketOptionName::MulticastInterface, 0);
    s->Bind(new IPEndPoint(IPAddress::Any,0));
 
    IPEndPoint* sender = new IPEndPoint(IPAddress->Any, 0);
    EndPoint* tempRemoteEP = __try_cast<EndPoint*>(sender);
    Byte buffer[] = new Byte[1024];
    Console::WriteLine(S"Waiting on socket.");
    s->ReceiveFrom(buffer, 0, 1024, SocketFlags::None, &tempRemoteEP);
 

I see the debug WriteLine I put in that it is waiting on the socket. I'm using Wireshark to watch for IGMP Queries/Reports on the wire and see IGMP
messaging, but my test module is not receiving these. I've tried various
other Socket Options, etc. and haven't had any success. I've read some
info on Bind that a 0 causes Bind to generate a enphemoral port number.
Since I'm trying to do Raw IP do I bind or do I need some value other than
0 for bind? I haven't been able to find any examples or info anywhere on
the Web and I've fallin into the mode of just trying various options from
the Socket Class. Kinda like rolling dice. Any one have any experience
in setting up to receive Raw IP with MS VC++?

This is an update to my post for information:
I found reference to the Socket.I0Contro l() function that allows a code
as a parameter. One of the codes I found reference to at the MSDN
URL : <http://msdn2.microsoft .com/en-us/library/system.net.sock ets.iocontrolco de.aspx>.
This identifies an IOControlCode of ReceiveAllIgmpM ulticast.
However I get a compile error of not a class of namespace on IOControlCode.
