+4  Q: 

How can my C# Windows app be notified of changes in network status without polling?

I would like to be notified when the computer's network connection is established (has a valid IP address) and I would like to do this without polling. Is there a Windows API that can provide these notifications?

+2  A: 

I would start with the System.Net.NetworkInformation.NetworkChange.NetworkAvailabilityChanged event.

Also WMI events might be possible, fired on changes to the set of Win32_NetworkAdapter or Win32_NetworkConnection instances.
