In this blog you will learn how to parse a JSON file from a File picker and populate the items in a ListView (UWP App).

1. Create a new UWP project in Visual Studio 2015,
   
   
   
   
2. We have a JSON file in the Documents folder which contains list of 10 countries and their country codes as below. The keys here are “Country” and “Code”.

4. To read and parse information from the class we need to install a Nuget Package. Here we are installing Newtonsoft.JSON, a popular JSON framework from NUGET package manager.
   
   
   
   
5. Create a ListView in the MainPage.xaml to hold the list of items as below,

7. Call the method in the Main method as below,
