Not reliable, don't use it.

If you have a Socket.Receive in progress then it will return either a zero
or an exeception. If you're using BeginReceive then your callback method
will be invoked and when you call EndReceive either a zero or an exception
will be the result.

There is no Close notification other than those, however you will find
that for almost every purpose they work just fine.

Hi,

In VB6 Winsock control there is an Event called 'CLOSE' which indicates that
the connection has been terminated. In vb.net, the sockets class exposes
a CONNECTED property that can be used to determine the connection status.
However is there any way of being notified via some kind of callback mechanism
about the connection being terminated...
