  1. When creating classes be sure to:
    1. Ensure the class in the root namespace. This can be done in one of two ways. Either by adding the class in the project, i.e. scenario, or by adding the class to the business classes folder and removing the ".Business_Classes" designation from the namespace.
  2. Open the main window (MainWindow.xaml) in designer mode (right-click and click "View Designer" or press Shift-F7 to go to designer mode).

6.2 Restaurant Assignment: Final Steps

Fix Bugs

Change the breadbasket capacity value which is passed into the Restaurant's constructor from the newRestaurantButton_Click() method from 30 to 45. Ensure that the created Basket objects now contain the new value of 45. Once you have proven that the code works as intended, change the value in the newRestaurantButton_Click() method back to 30.
