c# - ExecutionEngineException in Windows Phone device during navigate to a page -


i have error of class executionengineexception. when navigate page:

 private void friendsmaintxt_tap(object sender, system.windows.input.gestureeventargs e)     {         navigationservice.navigate(new uri("/view/map/usermap.xaml?type=users", urikind.relative));     }  protected override void onnavigatedto(navigationeventargs e)         {             base.onnavigatedto(e);             if (navigationcontext.querystring["type"] != null) //executionengineexception here             {                 typemap = navigationcontext.querystring["type"];             }        }

i have error wp8 device, in emulator never have. after error call

private void rootframe_navigationfailed(object sender, navigationfailedeventargs e)         {             if (debugger.isattached)             {                 debugger.break();             }         }

this exception can occur during garbage collection, how can influence process in wp?

any ideas.

thanks in advance!

i had exception occurring @ random. problem went away after deleted number of breakpoints set "when hit..." produce logging messages. apparently, vs2012 , / or runtime busy logging execute normally.
