如何在XML中保存WPF用户设置？

I'm a WPF newbie. I'm building a simple WPF app which require the user to login using the C# language. In the login page, user allow to tick on the "Remember me" and the "Sign me in automatically" check box but if the app closes, the setting will be reset to default. So, what I want is after every time the user ticks the checkbox and close the app, the setting must be saved. I'm a WPF newbie. I'm building a simple WPF app
