Create a C# application that accepts the user input for the following items: - Item Name, Quantity and Unit Price. To calculate the amount due, you will need to choose a shipping method. For Priority (same day shipping), a fee of $20 will be charged. For Overnight shipping, a fee of $15 will be charged. For Standard shipping, a fee of $5 will be charged. For in-store pick-up, there is no fee charged (may be in future you may charge a storage fee if items not picked within 7 business days)

For basic validation, you may set the following limits Priority shipping fee = $20 Overnight shipping = $15 Standard shipping = $5 in-store pickup = $0 Minimum quantity = 1 Maximum quantity = 1000 Minimum price = $1 Maximum price = $100000 Credit Card Expiration date must be greater that todays date and not more than 4 years from today The other minimum validation should check all other details pertaining to the cheque and credit card
