IReferenceTrackerManager interface (

Defines the interface for a XAML object reference manager. Implement this interface to manage instances of IReferenceTracker on XAML objects.


The IReferenceTrackerManager interface inherits from the IUnknown interface. IReferenceTrackerManager also has these types of members:


The IReferenceTrackerManager interface has these methods.


Indicates that a garbage collection system has finished making all the calls it needs to IReferenceTracker::FindTrackerTargets; by this time, XAML has pegged all reference tracker targets that it wants to protect.

Indicates that a garbage collection system has finished with its collection process; at this point, XAML unblocks threads attempting to update tracked references.

Indicates that a garbage collector is performing a collection; when the collection is finished, the garbage collector calls FindTrackerTargetsCompleted.

Registers an IReferenceTrackerHost interface with XAML.


Obtain a reference to an implementation of this interface by calling IReferenceTracker::GetReferenceTrackerManager on a XAML object that implements IReferenceTracker.

There is only one instance of IReferenceTrackerManager for a process, and it may be called from any thread.
