Let's say that you want to merge Meals.xaml and Beverages.xamlin the same page, since they do the same functionality but only display different content. You can also merge the two event handlers of the button since they're also similar. Let's start step by step.

How to do this? We have multiple pages, and we want to give the user a way to get

between them. Let's build a simple navigation UI that will allow us to do just that.

1)Open the application we created together through the previous couple of posts.2) From the Solution Explorer, delete Beverages.xaml and Meals.xaml3) Create a new page by right clicking the project>Add>New Item>Windows Phone Portrait Page and name it Menu.xaml

6) Go to Menu.xaml.cs, where the parameter that was passed to from MainPage.xaml.cs. Add to the OnNavigatedTo, if it is not there add it.
