In doing my netduino networking code (UDP & TCP) I tried something that was suggested back in 4.2 to detect when the connection is broken due to the inherent limitations of the NETMF.

 

It was proposed to use the NetworkInformation.NetworkAvailabilityChanged event handler. Basically one defines the delegate method and in there depending on the e.IsAvailable property one would stop or resume network operations (tx/rx).

Microsoft.SPOT.Net.NetworkInformation.NetworkChange.NetworkAvailabilityChanged += new Microsoft.SPOT.Net.NetworkInformation.NetworkAvailabilityChangedEventHandler(NetworkAvailabilityChangedHandler);

I have no hardware yet so I was trying it on the emulator which is supposed to have already a "connection" to the host system. I placed a breakpoint on that event handler method but it never gets called.

private void NetworkAvailabilityChangedHandler(object sender, Microsoft.SPOT.Net.NetworkInformation.NetworkAvailabilityEventArgs e)        {            lock (this.threadLock)            {                if (e.IsAvailable)                {                    StartServices();                }                else                {                    StopServices();                }            }        }
