Create an application with a class named Contacts. The Contacts class should have properties for FirstName (string), LastName (string), Address (string), City (string), State (string), Zip (string), and Phone (string). Use the "Contacts.txt"(http://brucebauer.info/assets/IFSC1202/Contacts.txt) file as data for the application.

When the application starts, it should read the data from the file and create an a list containing an Contact object for each Contactss data. Rename the default Form1 to MainForm. The Lastname, FirstName of the list of Contacts objects should be displayed in a listbox on the applications MainForm. When the user selects a Name from the listbox, a modal second form named DetailForm should appear displaying that employees name, IDNumber, department, position, and an Exit Button. You will also create code to add, modify, delete, and save the Contacts List

Hint: To do this project, you will have to make your Contacts, Contact List, and selected index public so that code in the DetailForm and make changes. Use the following code

// Create List containing Retail Item Objects - Page 570 public static List contactlist = new List(); // Index of currently selected Retail Item (-1 means none selected) public static int selectedindex = -1;

and in the Contact Class

public class Contact
