           Summary: socket unusable in silverlight profile
           Product: Mono: Runtime
           Version: SVN
          Platform: x86-64
        OS/Version: openSUSE 10.3
            Status: NEW
          Severity: Major
          Priority: P5 - None
         Component: io-layer
        AssignedTo: dick at novell.com
        ReportedBy: sdelcroix at novell.com
         QAContact: mono-bugs at lists.ximian.com
          Found By: ---

in the SL profile, System.Net.Soclets.Socket is in the System.Net.dll assembly,
but the socket code in socket-io.c expect it in the system_assembly (System.dll
I guess)

socket_class = mono_class_from_name (system_assembly, "System.Net.Sockets",

you should be able to reproduce this crash by compiling this one-line sample
with smcs

using System.Net;
public class Test
        static void Main ()
                DnsEndPoint endPoint = new DnsEndPoint("", 4502);

here's the relevant trace snippet:
