In a C#, console application, create a class called Invoice that a hardware store might use to represent an invoice for an item sold at a store. An Invoice should include four pieces of information as instance variables. A part number (string), part description (string), quantity (int), and price per item (decimal). The class should have a constructor that initializes the four variables. Provide a property get and set accessor for each instance variable. Provide a method named GetInvoiceAmount that calculates an invoice amount and returns the answer as a decimal value. Write a console based test app names InvoiceTest that demonstrates class Invoice's capabilities.
