If you don't have a file named Program.cs, just add a new Class and name it Program.cs.

Then paste this code:

 using System;
 using System.Collections.Generic;
 using System.Linq;
 using System.Text;
 using System.Windows.Forms;

 namespace Sales {
     static class Program {

         /// 

         /// The main entry point for the application.
         /// 
         [STAThread]
         static void Main() {
             Application.EnableVisualStyles();
             Application.SetCompatibleTextRenderingDefault(false);
             Application.Run(new Form1());
         }
     }

 }
