Debugging on emulator succeeds, but debugging on windows phone 7 device, why?

1.       Check the OS version of the windows phone 7 device.

a)         [Phone] Settings->about

b)         On “about” page, click “more info” button

c)         You’ll see OS version: 6527.Mainline.

2.       Check the WPDT release version which your debug IDE is.

E.g. WP7 WPDT 6541

Conclusion:
