Hi David,

Based on my experience, the Udpclient is just a wrap for Socket. So that we
did not need to handle many socket related operation. But in nature, the
UDPclient is using Socket for underlying communication.
In my view, I think the difference is udpclient is easy use and socket
class will have more control over the socket.
To choose Udpclient or socket is based on your scenario, if the job can be
done in udpclient, I think we can use the udpclient because you will find
that it will need less code than socket class.
