WPF: how to close an application?

Question

WPF

There is a main window "MainWindow". In it, an instance of the "WindowAdmin" window was created

new WindowAdmin().Show();
Hide();

And the question is how to close this "WindowAdmin" window so that it not only hides, but stops debugging. In WinForms, this was solved by throwing the Application.Exit() code into the FormClosed event;

Answer 1

What is the problem with clicking on the window cross?
If you want the MainWindow to close after the WindowAdmin is closed, then call Close, not Hide.
