i have uploaded app.xaml contents. have not made changes in it.

there 2 potential causes of this.

1. the common x:class doesn't match mainpage.xaml namespace. make sure x:class in mainpage.xaml has correct namespace.

2. the second common cause of problem "build action" not set "page" mainpage.xaml!
