I tried to implement you code on my Windows Store Apps.I have used Newtonsoft.Json namespace in my application. I was able to parse json data into JArray. But i was not able to call the method item.GetObject() as you have shown in the video.
Here is my code that i have written.How can i Implement item.GetObject inside foreach loop so that i can bind the object in the ListviewItem.
Uri dataUri = new Uri("ms-appx:///Assets/team.txt");
StorageFile file = await StorageFile.GetFileFromApplicationUriAsync(dataUri);
string Value = await FileIO.ReadTextAsync(file);
JArray array = JArray.Parse(Value);
foreach (var item in array)
string name = item.ToString();
