design

don't use public fields
define and use at least one interface

core / domain / business logic

class library
contains all business logic
contains domain classes (customer, order, store, product, etc.)
documentation with <summary> XML comments on all public types and members (optional: <params> and <return>)
(recommended: has no dependency on UI, data access, or any input/output considerations)

customer

has first name, last name, etc.
(optional: has a default store location to order from)

order

has a store location
has a customer
has an order time (when the order was placed)
can contain multiple kinds of product in the same order
rejects orders with unreasonably high product quantities
(optional: some additional business rules, like special deals)

location

has an inventory
inventory decreases when orders are accepted
rejects orders that cannot be fulfilled with remaining inventory
(optional: for at least one product, more than one inventory item decrements when ordering that product)

product (etc.)

user interface

interactive console application
has only display- and input-related code
low-priority component, will be replaced when we move to project 1

test

at least 10 test methods
focus on unit testing business logic; testing the console app is very low priority
