4. Copy the URL of your Azure App Service instance into the mobile app code

#1.

In Visual Studio 2017, in the MyItems solution, locate select the App.xaml.cs file under the "MyItems (Portable)" project. (You may need to click the App.xaml file's triangle to see the App.xaml.cs file.)

Locate the line with: public static string AzureMobileAppUrl = "";, which should be around line 12.

#2.

Replace the empty string with the URL of your Azure App Service instance that you found in part 3 of this wiki (or find it in the Azure portal).

Make sure to make the URL https instead of http. This important to make the app run properly on iOS.
