Design and implement a C# desktop application (not a web-based or database application) that helps a bike service centre to manage their stock/ inventory records. The bike service centre allows their staff to get or take items out from inventory only between 9 am to 4 pm, 5 days a week (from Monday to Friday). Staff are allowed to only get tools or other items out of inventory only after being approved by an admin. However, the system should allow you to add items to inventory at any time. Currently the service centre is using a paper-based manual system to keep records of stocks. The application is to keep track of each stock item detail with the staff name details of "approved by and taken by". The stock/ inventory should be only accessible to the admin who has the "ONLY" power to approve the items to be added or deducted from inventory
