I connected the shield in netduino, and the shield to my laptop (or router), but the program, in debug, reach the first line:
SecretLabs.NETMF.Net.Wiznet5100 wiznet = new SecretLabs.NETMF.Net.Wiznet5100(SPI.SPI_module.SPI1, Pins.GPIO_PIN_D10);
but does not reach the second:
NetworkInterface networkInterface = NetworkInterface.GetAllNetworkInterfaces()[0];
Project attached.
