IWeakReferenceSource interface (weakreference.h)

Represents a source object to which a weak reference can be retrieved.


With only a few exceptions, weak reference support is on by default for Windows Runtime types that you consume or author in C++/WinRT, WRL, and C++/CX. Windows.UI.Composition and Windows.Devices.Input.PenDevice are examples of exceptions—that is, namespaces where weak reference support is not on for those types.

If you're authoring types, then see Weak references in C++/WinRT.


The IWeakReferenceSource interface inherits from the IUnknown interface.


The IWeakReferenceSource interface has these methods.
