Use the supplied sоlutiоn, seаrch fоr TODO then write the code аnd test the аpplication. Remember to Download the XXX and unzip. Open VehicleRepair.sln in Visual Studio 2022. Right-click on the RepairUI project and ensure it is 'Set as StartUp Project'. Answer as many questions as possible, partial credit will be granted. Run the application to perform testing as needed. When complete use File Explorer, WinZip or 7-Zip to .zip the directory with application files. Upload the .zip file as your answer to the last essay question. You are developing an application that allows users to capture details for vehicle repair program.  The user must select a repair type.  Next click details to enter the repair details, click OK will display repair details and click Close will close form.  Finally click the cost button to display repair cost.  Given the solution, which is a 3-tier application and uses class inheritance with a RepairBO base class, follow comments and write code to meet requirements: The user must select vehicle type for Details button click to open Details screen. When the user clicks Details, open the Details screen as modal. Should be able to change repair details until clicking OK and Close on Details screen. When the user enters details and clicks OK: Validate numeric values and display any errors using a message box. Populate values from screen into the business object. Display values from business object on the Main screen. When the user clicks Cost, use business object to determine and display the repair cost.
