Updating the WalksMainPage code-behind using C#

Now that we have created the CreateNewTrailDetails class that will be responsible for handling the automated UI testing using the UITest framework, our next step is to begin updating the underlying C# code within our WalksMainPage code-behind file in order to disable displaying our TwitterSignInPage ViewModel.

Let's take a look at how we can achieve this by following these steps:

1. Locate and open the WalksMainPage.xaml.cs file which is located within the Views folder, ensuring that it is displayed within the code editor, and enter the following highlighted code sections:

    //
