Help with Visual C# 2012 Programming Problem

For reference, this is Programming Problem Ch 10, #4 in Starting Out with Visual C# 2012 by Tony Gaddis.

The problem states "Design a class named Person with properties for holding a person's name, address, and telephone number. Next, design a class named Customer, which is derived from the Person class. The Customer class should have a property for a customer number and a Boolean property indicating whether a customer wishes to be on a mailing list. Demonstrate an object of the customer class in a simple application."

So far, I have made the person class and the customer class. But, I'm not sure what to do for the application.

Customer.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace HW12CH10_4
{
class Customer: Person
{
int _customerNumber;
bool _mailing;

//customerNumber property create
public int customerNumber
{
get { return _customerNumber; }
set { _customerNumber = value; }
}

//mailing property
public bool Mailing
{
get { return _mailing; }
set { _mailing = value; }
}
}
}

Person.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace HW12CH10_4
{
class Person
{
string _name;
string _address;
string _phoneNumber;

//name property
public string Name
{
get { return _name; }
set { _name = value; }
}

//addres property
public string Address
{
get { return _address; }
set { _address = value; }
}

public string PhoneNumber
{
get { return _phoneNumber; }
set { _phoneNumber = value; }
}
}
}

Program

/*In this program i created two classess person and Customer.Cutomer is derived class of Person.So Customer class can access Persons attributes and methods.It's a simple program to show derived class access parent class and display details.*/

using System;

//Peron class
class Person
{
public string _name;
public string _address;
public string _phoneNumber;

//name property
public string Name
{
get { return _name; }

set { _address = value; }
}
//Phone number property
public string PhoneNumber
