Public Property ShutdownMode As ShutdownMode

Property Value

ShutdownMode

A ShutdownMode enumeration value. The default value is OnLastWindowClose.

Examples

The following example shows how to configure ShutdownMode to specify that an application must be closed explicitly.

<Application
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    StartupUri="MainWindow.xaml"
    ShutdownMode="OnExplicitShutdown"
    >
</Application>

Remarks

Applications stop running only when the Shutdown method of the Application is called. Shut down can occur implicitly or explicitly, as specified by the value of the ShutdownMode property.

If you set ShutdownMode to OnLastWindowClose, Windows Presentation Foundation (WPF) implicitly calls Shutdown when the last window in an application closes, even if any currently instantiated windows are set as the main window (see MainWindow).

A ShutdownMode of OnMainWindowClose causes WPF to implicitly call Shutdown when the MainWindow closes, even if other windows are currently open.

The lifetime of some applications may not be dependent on when the main window or last window is closed, or may not be dependent on windows at all. For these scenarios you need to set the ShutdownMode property to OnExplicitShutdown, which requires an explicit Shutdown method call to stop the application. Otherwise, the application continues running in the background.

ShutdownMode can be configured declaratively from XAML or programmatically from code.

This property is available only from the thread that created the Application object.
