Properties

	Name	Description
	IsAlive	Gets an indication whether the object referenced by the current NullableWeakReference object has been cleared or garbage collected. (Inherited from NullableWeakReference)
	Target	Gets the object (the target) referenced by the current NullableWeakReference object. Set will only accept null. (Inherited from NullableWeakReference)
	TrackResurrection	Gets an indication whether the object referenced by the current WeakReference object is tracked after it is finalized. (Inherited from WeakReference)

Methods

	Name	Description
	Clear	Clears Action callback target. (Overrides NullableWeakReferenceClear)
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object)
	Finalize	Discards the reference to the target represented by the current WeakReference object. (Inherited from WeakReference)
	GetHashCode	Serves as the default hash function. (Inherited from Object)
	GetObjectData	Populates a SerializationInfo object with all the data needed to serialize the current WeakReference object. (Inherited from WeakReference)
	GetType	Gets the Type of the current instance. (Inherited from Object)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object)
	ToString	Returns a string that represents the current object. (Inherited from Object)
	TryInvoke	Attempts to invoke the delegate to a weak reference object.

Extension Methods

	Name	Description

Remarks

This class will store the information necessary so the callback object will have a weak reference to it. This information is compiled an can be quickly executed without the overhead of using reflection.
