Could you please guide me on how to deploy windows phone 8 apps on other windows phone for testing without phone developer account or any other means . Just deploy the .XAP in any other windows phone and test or for giving demo.
there can be many ways to deploy app on phone.. 1. by launching a beta version of the app and giving microsoft account of the people you want to send it. it will be a 90 days trial and then app will be removed. while this you can also update your app for testers.
here is the link which might help you
