A value that indicates how the application window is positioned at startup.


This property is not required. If you do not specify it in the out-of-browser configuration, the default value of CenterScreen is used.

This property is read-only at run time, but you can set it in the out-of-browser configuration. For more information, see How to: Configure an Application for Out-of-Browser Support.

You can set the Window.Top and Window.Left properties at run time only if WindowStartupLocation is set to Manual.
