Murach's Visual Basic 2015 Exercises 18-1 & 18-2: Create a Customer Maintenance application that uses inheritance / Modify the CustomerList class to inherit the List() class

18-1: In this exercise, you'll create a Customer Maintenance application that uses classes with the inheritance features presented in this chapter. This application works with two types of customers; retail customers and wholesale customers. Both customer types are derived from a Customer base class, both extend the Customer class by adding a property, and separate forms are used to add the two types of customers. To make this application easier to develop, we'll give you the starting forms and classes.

18-2: This exercise builds on the Customer Maintenance application you created in exercise 18-1 by modifying the CustomerList class so it inherits the .NET Framework's List() class.
