应用程序崩溃而未调用未处理的异常方法Windows Phone 8

Question

I am developing an app for both WP7 and WP8.
So i finished the WP7 part and it is working properly and now I have updated the target version to Windows Phone 8 and my app crashes without notifying anything.
In xaml designer it shows an error like:

Microsoft.Expression.DesignHost.Isolation.Remoting.RemoteException

I do not understand how to solve this as I have tried the methods available on internet telling to copy a .dll file from one location to another but that also didn't worked in my case.

Xaml of page before it crashes ...

Can anybody help me with this or at least guide me to where the problem is ...
