I am so surprised to find that there is no close notification in socket
class. Like OnClose in MFC CAsyncSocket. Any suggestions please ......

In many cases there can be no notification until you attempt to read or
write (and the operation fails).
Also, as the sockets are synchronous, there's not much sense to make such
notification.

I haven't actually done any socket stuff in .NET, but...don't you get the
end-receive notification, with a 0 value for the call to EndReceive, to
indicate closure of a socket?

I was going to say the same thing. That is what I would do.
