To run this sample
The project includes several class definitions. Customer is the base class, and contains only three properties. Four other classes are derived from the Customer class. Each inherits the properties of Customer, but adds another category of class member.
CustomerPropertySyntax is a modification of the Customer class that sets the AccountNumber property during construction. Once created, the AccountNumber cannot be changed.
CustomerWithConstructor is a modification of Customer that includes a constructor that sets all three properties during instantiation.
CustomerWithParameterizedProperty is a customization of Customer that adds a property that takes a parameter.
CustomerWithSharedMembers adds a shared property and a shared method to the Customer class.
