Closing Application on Error

In the constructor of my initial windows form class I would like to do some set up of various parameters. If errors occur during this setup I would like an error message to appear and the entire application to end. Unfortunately, the initial form appears and must be closed. I have tried adding a close() in the constructor but probably because the form has not been shown at this point this doesn't work. Some code snippets are as follows. Any ideas? TIA static void Main() { Application.Run(new Master()); } public class Master : System.Windows.Forms.Form { InitializeComponent(); // test new data Access class try { da = new DataAccess(); } catch (Exception err) { MessageBox.Show(err.ToString()); Close(); // note: doesn't work return; // returns but form is still displayed } ..... }
