Occurs after an end-user has logged off.
The event handler receives an argument of the EventArgs type.
Handle this event to execute custom code after a user has logged off. Note that if the LoggedOff event is raised as a consequence of an ASP.NET session ending, you cannot use XAF singleton instances such as XafApplication and Security System in the LoggedOff event handler. For details, refer to the XafApplication.LoggingOff event description.
