Answer 1

Try this

private void btnAdd_Click(object sender, RoutedEventArgs e)
{
    WebClient proxy = new WebClient();
    proxy.DownloadStringCompleted += new DownloadStringCompletedEventHandler(proxy_DownloadStringCompleted);
    proxy.DownloadStringAsync(new Uri(""));
}

And need to parse the returned JSON as below. In parameter to create instance of DataContractJsonSrrializer we are passing List of Student.

void proxy_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
{
    Stream stream = new MemoryStream(Encoding.Unicode.GetBytes(e.Result));

    DataContractJsonSerializer obj = new DataContractJsonSerializer(typeof(List<Student>));
    List<Student> result = obj.ReadObject(stream) as List<Student>;
    lstStudents.ItemsSource = result;
}
