Compact Framework Sockets Question

I don't see a Compact Framework newsgroup so I am just going to post it here.

We are porting a .NET 2.0 program to the compact framework and the
application involves the sending and receiving of multicast packets. We
noticed that even though the property Socket.MulticastLoopback exists in
object browser under "System [Compact Framework]", it complains at compile
time that

'System.Net.Sockets.Socket' does not contain a definition for
'MulticastLoopback'

According to the MSDN documentation online, this property is supported by
the compact framework and we are using the latest service pack of CF2.0.

Any ideas? If this property is indeed not included in the CF, how might we
configure the socket so that (we have already tried

sock.SetSocketOption(SocketOptionLevel.IPv4,
SocketOptionName.MulticastLoopback, 1);

which throws during runtime) we can allow multicast packets to loop back?

Actually, the group you're looking for is this one:

microsoft.public.dotnet.framework.compactframework

I don't see it on the web newsgroup browser, could it be that it is not a
managed newsgroup?

If you mean managed by Microsoft, that may be true. I have no way of
telling, since I don't have whatever subscription you have that means
Microsoft will eventually answer your questions in the managed newsgroups.
