C#:For today's lab you will be creating a store inventory management system. Your program will have to have the following elements. It should allow any number of customers to shop at the store using names to identify each one. The user should be able to select which one is the current customer. The system must contain a list of at least 50 items (repeats are allowed) that can be purchased by the customers.

For a customer to make a purchase they must transfer the items they wish to buy to their own shopping cart. (A Shopping cart list should be maintained for each customer). The user should be able to switch between customers without losing the contents of each customer's cart. The user can select complete purchase and will be presented with a total for that users purchases. Customers should be able to remove items from their cart and return them to the stores inventory. . A customers cart should be removed after her/his purchase is complete.
