The NullableWeakReference type exposes the following members.

Constructors

	Name	Description
	NullableWeakReference	Creates a NullableWeakReference

Properties

	Name	Description
	IsAlive	Gets an indication whether the object referenced by the current NullableWeakReference object has been cleared or garbage collected. (Overrides WeakReferenceIsAlive)
	Target	Gets the object (the target) referenced by the current NullableWeakReference object. Set will only accept null. (Overrides WeakReferenceTarget)
	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	Sets Target to null so subsequent calls to Target returns null
	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)

Extension Methods

	Name	Description
	GetEnumValueOrDefault	Gets the enumeration constant for value, if defined in the enumeration, or a default value. (Defined by EnumExtensions)
	GetEnumValueOrDefaultT	Gets the enumeration constant for this value, if defined in the enumeration, or a default value. (Defined by EnumExtensions)
