IReferenceTrackerHost::DisconnectUnusedReferenceSources method (microsoft.ui.xaml.hosting.referencetracker.h)

Requests that the host perform garbage collection and remove all unnecessary reference sources.

Syntax

HRESULT DisconnectUnusedReferenceSources(
  [in] XAML_REFERENCETRACKER_DISCONNECT options
);

Parameters

[in] options

0 or 1.

1 indicates that an application suspend is in progress.

Return value

If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Remarks

This method is expected to potentially cause the reference source to call DisconnectFromTrackerSource, but it is not necessary to call IUnknown::Release immediately on the tracker source. In the CLR, this call triggers a garbage collection, but not a WaitForPendingFinalizers. When flags is one, the garbage collection is executed in the GCCollectionMode.Optimized state.
