 Remarks
RemarksUse UdpClient when the primary purpose is to receive data.
The Client socket can be bound to a specified interface on a machine with multiple interfaces by specifying the interface in the ConnectionString (Example: "Server=localhost:8888; Port=8989; Interface=127.0.0.1")
The Client socket can be used just for transmitting data without being bound to a local interface by specifying -1 for the port number in the ConnectionString (Example: "Server=localhost:8888; Port=-1")
