Is it possible to run multiple instances of same application on Windows Phone 7.5 ? When I deactivate current instance and try to run a new instance via Start menu, the backround app disappears, and the new one starts in foreground with initial screen.
Is Application State preserved between such “restart” ?
No, it’s not possible to run multiple instances of an application in WP. When you start the application as you describe it counts as a restart of the application and no state is saved. Have a look at http://msdn.microsoft.com/en-us/library/ff817008(v=vs.92).aspx for detailed information.
