That might work - I don't know, I have already changed the code to use
Socket.BeginConnect/EndConnect which connects instantly using the same IP
address string. But that brings up another question...

In the desktop .NET framework WaitOne(delay in ms) can be used after
BeginConnect to limit the time allowed for a conection attempt. But the CF
version of WaitOne does not accept a time limit. I have seen suggestions
that Thread.Sleep be used instead, followed by testing a boolean that is set
on in the callback if the EndConnect executes normally. If this bool is not
set after Sleep then the connection has not completed.

My question is, in that case isn't the callback thread still waiting on
EndConnect? And if so how can the program terminate it - preferably leaving
the Socket in a state that will allow the user to make another connection
attempt. (It is my impression that "desktop" WaitOne kills the thread if it
times out, but I could be mistaken about that also.)
