Returns an object that you can use to enumerate the items in the view.
Assembly: PresentationFramework (in PresentationFramework.dll)
Enumerator instances are typically used for making asynchronous checks of the contents of a collection, or in this case, the contents of the view. For example, if you are about to start a foreach iteration over the contents of the view, it may be better to obtain an asynchronous copy to ensure that the length of the view items does not change unexpectedly midway through the loop.
