+Summary: NullReferenceException  from listenSocket.SetSocketOption() which working in 1.1.8.3.
+
+It's actually System.Net.Sockets.
+
+The following code shows a NullReferenceException coming out of 
+listenSocket.SetSocketOption() where it previously worked. It prints...
+
+Good so far...
+Bollocks!
+
+try
+            {
+                Socket listenSocket = new Socket
+(AddressFamily.InterNetwork,  SocketType.Dgram, ProtocolType.Udp);
+                listenSocket.SetSocketOption(SocketOptionLevel.Socket, 
+SocketOptionName.ReuseAddress, 1);
+                listenSocket.Bind(new IPEndPoint(IPAddress.Any, 
+DiscoveryPort));
+                Debug.Assert(listenSocket != null);
+                Console.WriteLine("Good so far...");
+                listenSocket.SetSocketOption(SocketOptionLevel.IP, 
+SocketOptionName.AddMembership, new MulticastOption(IPAddress.Parse
+("224.4.0.1"), IPAddress.Any));
+            }
+            catch (NullReferenceException)
+            {
+                Console.WriteLine("Bollocks!");
+                throw;
+            }
+            catch (Exception)
+            {
+                Console.WriteLine("Damn!");
+                throw;
+            }
