An event in the pending notifications queue when the presence of an entity
the current user is watching changes.
This event is raised if there is an IM client in the current session and the
presence of an entity in the current user's roster changes, or the client
has requested for the presence of an entity to be watched.
Gets the SnapshotId of the affected object after the change. If
this is null, it indicates that the SnaphotId is unknown. It is
expected that the application will reload an object's snapshot when it
receives an event with an unknown SnapshotId.
Below are examples in JSON and XML formats. All examples are shown with all inherited members. Quoting when required is part of the examples, but you must obviously populate with your own data.
