Hi :)

Assigning the multicast interface ID (MulticastInterfaceId) of the
UdpDiscoveryEndpoint.TransportSettings doesn't work on Linux, and has
inconsistent behavior on Windows, depending on the runtime used.

Under Windows, when using the Microsoft .NET 4.0 runtime:
  - If I specify an invalid interface ID, I get a
System.InvalidOperationException exception.
  - If I specify a valid interface ID, multicast packets are sent though that
interface.

Under windows, when using the Mono 2.8.2 runtime:
  - I can specify an invalid interface ID: no exception is risen.
  - If I specify a valid interface ID, multicast packets are sent though that
interface.

Under Linux, when using the Mono 2.8.2 runtime:
  - I can specify an invalid interface ID: no exception is risen.
  - If I specify a valid interface ID, multicast packets are sent though "eth0"
interface, event if I specify my valid "eth1" interface.

Reproducible: Always

Steps to Reproduce:
See bug details.
Actual Results:  
See bug details.

Expected Results:  
See bug details.

I used Wireshark on Windows and tcpdump on Linux to confirm that multicast
packets  were sent using the correct (or incorrect) interface.
