Silverlight application life-cycle

hi,

Silverlight is running on client , not on server just like asp.net application.
there is no such life cycle in silverlight but just like asp.net some events are fired in specific order.
1) first call app constructor (app.xaml)
2) after this application_start execute
3) main page contructor and initialize component.
4) SizeChanged event and Then the LayoutUpdated event.
5) Silverlight app exit or close the Browser the App's Application_Exit event will be executed

please refer.
