Wuv Luv Air is growing! WLA now has an airport in Norway. Sigurd, a new traveler, is taking a trip to from Oslo, Norway, to Wausau, WI. Wuv Luv has also acquired a biplane. We need to find the location of that biplane, and calculate the total mileage of each of the airplanes at the airport.
Define the new classes and the list as needed, and create instances of these objects and set their fields. Create the methods in the MainWindow as shown in the diagrams.
Create any button(s) and button click event handler(s) in the WPF window designer (if specified in the class diagram).
