This event can be used to persist any `string` state to the `State` property of the `BackgroundingEventArgs` object, which the OS will preserve until it's time to resume the window.

 ### Mac Catalyst
 
 Mac Catalyst doesn't support resizing or repositioning windows programmatically. However, a workaround to enable resizing is to set the `MinimumWidth` and `MaximumWidth` properties to the desired width of the window, and the `MinimumHeight` and `MaximumHeight` properties to the desired height of the window. This will trigger a resize, and you can then revert the properties back to their original values:

 ## Decouple window management from the App class
 
 Window management can be decoupled from the `App` class by creating a class that implements the <xref:Microsoft.Maui.Controls.IWindowCreator> interface, and adding your window management code in the <xref:Microsoft.Maui.Controls.IWindowCreator.CreateWindow%2A> method:
