Remarks

A weak reference refers to an object but still allows it to be garbage collected.

A persistent weak reference can be used in the following instances:

when a persistent object needs to refer to another object whose type cannot be specified at the time the program code is written;
when you need to create a reference to an object but allow it to be garbage collected.

The object referenced by the XPWeakReference is specified by the XPWeakReference.Target property.
