windows phone App is not starting after changing the namespace

I am developing an app that was working fine till 2 days back. But when today I started it again its not starting. When I launch It, it exits as soon as it is started. I have changed nothing in my code since last launch still. I see no pointer about it. Neither any exception nor anything else. My recent changes include change in app icon & package name. But I had run the app after these changes. don't know whats wrong?

this is only thing I can provide:

Solution

  • found the solution, the reason was the change I made in namespace:

    After changing the namespace, you should update the startup object as well. Go to Project>Properties then under startup object select the object that includes the updated namespace.App object.
