{

    RoutedPropertyChangedEventArgs<Color> newEventArgs =
        new RoutedPropertyChangedEventArgs<Color>(oldColor, newColor);
    newEventArgs.RoutedEvent = ColorPicker.SelectedColorChangedEvent;
    RaiseEvent(newEventArgs);
}
Protected Overridable Sub OnSelectedColorChanged(ByVal oldColor As Color, ByVal newColor As Color)

    Dim newEventArgs As New RoutedPropertyChangedEventArgs(Of Color)(oldColor, newColor)

Comentarios

No se puede establecer este valor en un RoutedEventArgs que ya se ha enrutado (por ejemplo, si se han obtenido los argumentos a través de un controlador).You cannot set this value on a RoutedEventArgs that has already been routed (for instance, if you obtained the arguments through a handler). Si intenta hacerlo, se generará una excepción.Attempting to do so will generate an exception. Solo se puede establecer en una instancia que todavía no se haya usado para generar una invocación del evento.You can only set it on an instance that has not yet been used to generate an invocation of the event.

El valor de RoutedEvent no se puede null en ningún momento.The value of RoutedEvent cannot be null at any time.
