I tried today with HelloWorldServer_MF and HelloWorldClient_MF on default emulator using .Net Micro Framework 4.3. All of them gave me a SocketException with a HResult code of 4278190080. I am just wondering is that possible to run DPWS WCF services on a emulator? If not, how can I test it? I am working on a project may want to deploy SOA to crossbow imote 2 boards with .Net Micro Framework. Thanks a lot.
