Hi guys, i'm tring to make an application that run in a single window using kinect.

I'm merging project with the KinectUI.

After all the project start and run well if I use the mouse, but using the Kinect I have a crash every time I'm going to open a new page.

I have 3 buttons with magnetic sets on true, the application crash after the progress bar loading.

What could be the problem?

Thanks at all who will answer.

Visual Studio bring me here:


                foreach (FrameworkElement element in MagneticsControl)
                    // Getting the four corners
                    var position = element.TransformToAncestor(rootVisual).Transform(new Point(0, 0));
                    var p1 = new Vector2((float)position.X, (float)position.Y);
                    var p2 = new Vector2((float)(position.X + element.ActualWidth), (float)position.Y);
                    var p3 = new Vector2((float)(position.X + element.ActualWidth), (float)(position.Y + element.ActualHeight));
                    var p4 = new Vector2((float)position.X, (float)(position.Y + element.ActualHeight));
