/// </summary>
void ITransformProvider.Rotate(double degreesToRotate)
{
    throw new InvalidOperationException("Operation cannot be performed.");
}

Private Sub Rotate(ByVal degreesToRotate As Double) Implements ITransformProvider.Rotate
    Throw New InvalidOperationException("Operation cannot be performed.")
End Sub

Remarks

An object cannot be moved, resized or rotated such that its resulting screen location would be completely outside the coordinates of its container and inaccessible to keyboard or mouse. For example, when a top-level window is moved completely off-screen or a child object is moved outside the boundaries of the container's viewport. In these cases the object is placed as close to the requested screen coordinates as possible with the top or left coordinates overridden to be within the container boundaries.
