Closed Issue: ListPicker with ListPickerMode set to "Full" causes recovery after tombstoning to fail [8137]

On Windows Phone 7, if the application is tombstoned while displaying a page containing a ListPicker, with ListPickerMode set to Full, and later re-activated by the user, a System.InvalidOperationException exception is thrown in the page constructor (during execution of the function System.Windows.Application.LoadComponent(this, new System.Uri("/\r\n;component/\r\n.xaml", System.UriKind.Relative)); in the generated \r\n.g.i.cs.

The message in the exception is:
"To get SystemTray visibility the RootVisual must be a PhoneApplicationFrame and its Content must be a PhoneApplicationPage"

The stack trace of the exception shows:

Workaround:
The exception doesn't occur if ListPickerMode is set to either Normal or Expanded. So, instead of selecting Full, select one of the other two modes and set ItemCountThreshold to 0 (zero). This will cause the ListPicker to operate in Full mode.
Comments:

ListPickerMode is now read-only in the latest toolkit.
