Gets or sets the width of the rectangle.
Assembly: System.Windows (in System.Windows.dll)
You can set this value in XAML, but only as part of the attribute syntax for properties that take a Rect, or as initialization text of a Rect object element. See XAML sections and Remarks sections of Rect.
width and height can be negative if they are specified in XAML as part of the attribute string, with the result that the direction that the width or height applies to is inverted. For instance, a height of -20 will produce a Rect where the X,Y point is now the bottom left corner. However, the managed API does not permit negative values for width and height. You should adjust the coordinate reference of x,y, width and height such that the Rect can be specified using non-negative values.
