Parameters

availableSize

The available size that this element can give to the child. You can use infinity as a value to indicate that the element can size to whatever content is available.

Return Value

A Size structure that has the Height and Width properties both equal to zero (0).

This method always returns a Size that has a width and height of zero (0), because Popup content is not located in the visual tree of its logical parent or PlacementTarget. The child content is created in a different window that has its own visual tree.
