Occurs just before an application shuts down and cannot be canceled.
(in System.Windows.dll)
Visual Basic (Declaration)
Public Event Exit As EventHandler
Dim instance As Application
Dim handler As EventHandler
AddHandler instance.Exit, handler
public event EventHandler Exit
<Application Exit="eventhandler"/>
You can detect when an application shuts down by handling the Exit event. This allows your application to perform common application shutdown tasks, including saving data for the next application session and logging.

An Exit event handler should not include long-running, re-entrant, or cyclic code, such as resetting the Silverlight plug-in's Source property. |
The following code shows how to handle Exit using markup and code-behind.
<Application
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
x:Class="SilverlightApplication.App"
Startup="App_Startup"
Exit="App_Exit">
</Application>
Partial Public Class App
Inherits Application
Public Sub New()
InitializeComponent()
End Sub
Private Sub App_Startup(ByVal o As Object, ByVal e As StartupEventArgs) Handles Me.Startup
' The application has started.
End Sub
Private Sub App_Exit(ByVal o As Object, ByVal e As EventArgs) Handles Me.Exit
' The application is about to stop running.
End Sub
End Class
using System; // EventArgs
using System.Windows; // Application
namespace SilverlightApplication
{
public partial class App : Application
{
public App()
{
InitializeComponent();
}
private void App_Startup(object sender, StartupEventArgs e)
{
// The application has started.
}
private void App_Exit(object sender, EventArgs e)
{
// The application is about to stop running.
}
}
}
