Assembly: Microsoft.Phone (in Microsoft.Phone.dll)

The available size that this element can give to child elements. Infinity can be specified as a value to indicate that the element will size to whatever content is available.
Windows Phone will always lay out the RootVisual in portrait orientation with the origin at the top-left corner of the physical screen. However, the PhoneApplicationFrame class switches the Width and Height during the arrange and measure passes, in addition to applying a rotate transform, in order to display content in landscape mode.
