you have to handle Application_DispatcherUnhandledException when application crashed and CurrentDomain_UnhandledException when Unhandled occured.

private void Application_DispatcherUnhandledException(object sender,DispatcherUnhandledExceptionEventArgs e)
{
    if(ExceptionView != null)
        ExceptionView.ErrorLoger(e.Exception);
   e.Handled = true;
}


void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e)
{
    var ex = e.ExceptionObject as Exception;
    if(ExceptionView != null)
        ExceptionView.ErrorLoger(ex);
}

and at App.XAML use Application_DispatcherUnhandledException handler.

like:- DispatcherUnhandledException="Application_DispatcherUnhandledException"
