Описание
Изменение абсциссы прямоугольника. Значение "Canvas.Left" атрибута Storyboard.TargetProperty было взято в скобки, поскольку оно состоит из двух слов. Анимация будет воспроизводиться бесконечно ( RepeatBehavior="Forever" ), а прямоугольник будет курсировать от одной точки к другой и обратно ( AutoReverse="True" ).
