Button to open a new form and close itself

Hslldm asked:

Open original thread
I added a button and wrote;

private void Button_Click_1(object sender, RoutedEventArgs e)
            MainWindow_1 mw = new MainWindow_1();
            MainWindow mw1 = new MainWindow();
//mw.Close(); doesnt work as well//
by this i open a new form but mw doesn't close.

How can i do that?
