Hi I'm using the latest 2010 release.
On my window I have a radchart with Pyramid3DSeriesDefinition.
In my code I'm adding the the camera extension but it gives me a null reference exception on runtime.

Above mentioned is the stack trace.
Below mentioned is the code that I'm using in the radChart_Loaded event.

var cameraExtension = new CameraExtension();
radChart.DefaultView.ChartArea.Extensions.Add(cameraExtension);
