app crash when toast notification click(phone pin is locked

Question

Hi friends,

 

we developed one windows phone app and implemented push notifications. its working properly in all the scenarios except when the phone is pin locked.

 

my problem is when app receives the toast notification if the phone is pin locked, then user taps on toast i am getting "System.Net.WebException" .

 

its working fine in windows phone 7.

 

please provide me some suggestions.

 

thanks in advance.
