There was a previous issue posted about ArrowGaugeIndicator, but I have found a problem with NeedleGaugeIndicator. I have only the reference to the "RadControls for Windows 8". ArrowGaugeIndicator works, but not NeedleGaugeIndicator. It adds in the XAML with Intellisense, but the line is highlighted with "Object reference not set to an instance of an object."
Update.. I added all of the binaries singularly and I still get the same issue.
