NOTE: PLEASE DO THAT ON C# CODING AND COMPLETELY DONE. ONE OF THE EXPERTS SEND ME THE FIRST TWO PARTS AND DIDNT FINISHED THE REST!!!!!!!!

Assignment Objective The purpose of this assignment is to practice flexible design, read a csv file from disc, store the data in a collection of objects and print the results in natural and sorted order. Your Task 1. Name your project COMP3602Assign04 2. Define an abstract class named Item 3. Implement the following public property methods in class Item: (use appropriate datatypes) Description (read-write) Price (read-write) Sku (read-only) 4. Include the necessary code to support sorting by Price descending in Item 5. Define a class named GroceryItem in a separate source file that inherits from Item 6. Ensure that the following public property methods are available for GroceryItem: objects (use appropriate datatypes): Description (read-write) Price (read-write) Sku (read-only) ExpirationDate (read-only) 7. Declare class GroceryItem's ExpirationDate as a DateTime type 8. Define a class named ApplianceItem in a separate source file that inherits from Item 9. Ensure that the following public property methods are available for ApplianceItem: objects (use appropriate datatypes): Description (read-write) Price (read-write) Sku (read-only) ApplianceType (read-only)

10. ApplianceType should be of an enum type that you create with the following labels: Washer, Dryer, Dishwasher, Oven, Range, Refrigerator 11. Define a class named ItemList (derived from List) in a separate source file Implement the following calculated property method in class ItemList: TotalPrice 12. Read the included file (items.csv), parse the data and populate a collection of Objects, being sure to note whether they are groceries or appliances. groceries.csv file contents: 4L Milk,345345,3.87,2019/10/14 500g Cottage Cheese,452255,4.28,2019/11/9 1 Tin Mushroom Soup,744566,0.99 SuperValu QuickWash, 997546, 499.99, Washer 15kg Dog Food,234434,29.99,2021/2/19 RayMag Crystal Clean Dishwasher, 993442, 649.99, Dishwasher RayMag Crystal Clean Dishwasher (Sale), 993442, 449.99, Dishwasher 13. Obtain the file path from a command line argument. Display error messages for missing argument or file not found. 14. Display a summary in natural and sorted order by iterating through the populated collection. Use interpolated strings to format the output. Place your output code in a static method in a dedicated output class. For full marks, make your output look exactly like the screenshot at the end of the requirements. 15. In a block comment at the top of Program.cs, write a few sentences about some pros and some cons of the design of this application.

For all your code, be sure to: Comment your code intelligently (no need to comment the obvious)
