It looks like the the ArcGIS runtime WPF API only supports looking for GPS devices connected to a serial port for location. 
Is there anyway of getting location based on wifi or cell triangulation if gps is not available?
Or do I need to implement my own code using .Net 4 location api?
System.Device.Location -  http://msdn.microsoft.com/en-CA/library/system.device.location(v=vs.100).aspx
If so has anyone done this with success or have a sample?
