Is this a WinForm application or a WPF application?

Check you star up Form.
You need to close that to close you application if that form is hidden in background so your process is still running.
You can use application.exit() to close you application.
You can check you stat up Form in project property application tab.

Another option that you can specify is that change shutdown mode in application tab to when last form is close.
