ExtendedWeakReference Class
Represents an extended weak reference, which references an object but still leaves it prone to garbage collection.
Namespace: Microsoft.SPOT
Assembly: Microsoft.SPOT.Native (in microsoft.spot.native.dll)
When the object referred to by the extended weak references has no live references to it, it will be stored in a serialized format. Thus, the target of an ExtendedWeakRefernence object must be serializable. You use a selector and an identifier to identify a group of one or more weak references. The selector should be a type known only to the user of the ExtendedWeakReference object. Note that you can use the same selector with multiple IDs to create groups of ExtendedWeakReference objects.
