multicast

[develop-wm9]

Hello

I have developped a software to listen UDP multicast and I
have problem when I try to listen different multicast
address and the same port.

It's OK for the first listen but when I try to initialize
a second listen I have an error message
"Only one usage of each socket address (protocol/network
address/port) is normally permitted." Error = 10048.

Is it possible, with .NET, to listen more multicast
address on the same port ? (It is possible in Win32 and
C).

Thanks
