Gets or sets a list of containers to which this NavigationFrame can navigate.
An IEnumerable object that contains objects to which this NavigationFrame can navigate.
NavigationFrame can navigate to any suitable container regardless of the PrefetchedSources list. Setting the PrefetchedSources list allows you to ignore all navigation properties and methods and cycle through containers just by calling the frame’s GoBack and GoForward methods.
Assigning a list to a PrefetchedSources property automatically executes actions specified by the NavigationFrame.PrefetchedSourcesOptions property.
