Final answer:
In WPF, a series of events are fired during the application shutdown process. These events allow you to perform certain tasks before the application completely shuts down.
Step-by-step explanation:
In WPF, a series of events are fired during the application shutdown process. These events are triggered in a specific order, allowing you to perform certain tasks before the application completely shuts down. The events fired for application shutdown in WPF are as follows:
Exit: This event is fired when the application is about to exit. You can use this event to perform any necessary cleanup tasks.
SessionEnding: This event is fired when the user is ending the session or logging off. It provides you an opportunity to save application data before the session ends.
Deactivated: This event is fired when the application loses focus or is minimized. You can use this event to handle any necessary logic before the application becomes inactive.
Closed: This event is fired when the main window of the application is closed. It signifies the final step of the shutdown process.
In WPF, the application shutdown process includes a series of events such as Exit and SessionEnding. These events allow developers to perform necessary tasks like saving the application state and releasing resources before the application closes.
When an application is shutting down in Windows Presentation Foundation (WPF), a series of events are fired in a specific order. These events allow developers to perform clean-up tasks and saving state before the application completely terminates. The event sequence during application shutdown typically includes:
Exit: This event is fired by the Application class when the application is about to stop running. It can be handled to perform tasks such as saving application state and releasing resources.
SessionEnding: If the shutdown is initiated by a user logoff or system shutdown, the SessionEnding event can be raised, giving an opportunity to prevent the shutdown or to save user data before it occurs.
To properly handle these events, developers should subscribe to them using event handlers in the Application class of their WPF application. It is important to note that any long-running tasks in these event handlers can delay the shutdown process, and that applications should be designed to handle shutdown scenarios gracefully.
