hello yesh88,
Which Version did you used for developing your app(Windows phone 7.0,7.1,7.5 etc..)
Compatibility depends upon the version you are opting for development..
For developing Cross-platform apps(targeted to multiple mobile OSes) try Cordova(Phonegap),its a 3rd party tool.
You can download it here
