Invoice App

Hello,

I need an app made in Visual Studio Basic doing a Windows Form Application. In the code also needs to be basic comments on what certain parts of the code are doing. The instructions of the app needing to be created is below.

Thank you in advance!

9.6 (Invoice Class) Create a class called Invoice that a hardware store might use to represent an invoice for an item sold at the store. An Invoice
should include four pieces of information as instance variables—a part number (type String), a part description (type String), a quantity of the item being
purchased (type Integer) and a price per item (type Integer). Your class should have a constructor that initializes the four instance variables. Provide a
property for each instance variable. If the quantity is not positive, it should be set to o. If the price per item is not positive, it should be set to o. Use
validation in the properties for these instance variables to ensure that they remain positive. In addition, provide a method named DisplayInvoiceAmount that
calculates and displays the invoice amount (that is, multiplies the quantity by the price per item). Write an app that demonstrates class Invoice’s
capabilities.
