Description Ryan Williams 2016-10-11 06:57:14 UTC
In .NET you can pass a null IPEndPoint parameter into the Receive method but in Mono you can't.

// Works in .NET but not in Mono
var udpClient = new UdpClient(11000);
IPEndPoint remote = null;
udpClient.Receive(ref remote);

// Workaround from the Microsoft documentation
var udpClient = new UdpClient(11000);
var remote = new IPEndPoint(IPAddress.Any, 0);
udpClient.Receive(ref remote);
