A WPF rectangle will render with zero size when Stretch = None

I just ran into this problem and also found an existing post on SO asking about the same issue.

Summary:

The Rectangle's Stretch property when setting it to NONE ... According to MSDN, the definition for this value is "The content preserves its original size." Look at the code below. When I set Stretch = NONE on the rectangle, it disappears.

Someone looked at the Rectangle ArrangeOverride method which has this key section:

<code>caseStretch.None:         

{ this._rect.Width=(this._rect.Height=0.0); break; }

(sorry for the bad formatting, I can't get it to paste neatly)

So it seems that when Stretch is None there is only empty rectangle. This doesn't seem to make sense.

The SO post I mentioned is: https://stackoverflow.com/questions/5822662/rectangle-stretch-property-behavior
