title: Detect network connectivity from a WPF/XBAP Application?
body: <p>Is there any way to determine if an XBAP (WPF hosted in a browser) application has network connectivity? If not, how would a traditional windows client written in C# and .NET determine if it has connectivity?</p>
  
  <p>Basically the use case is an XBAP application running on a mobile laptop connected to an intranet via WiFi. The laptop will not have a connection to the Internet. The WiFi connection may or may not be there depending upon where the user is at the time. </p>
