how to poll server and check for updates
<p>i have this code which does GET from server and retrieves JSON.</p>

<pre><code>private async void JSON_click(object sender,RoutedEventArgs e)

    { 
       var client=new HttpClient();
       client.MaxResponseBufferSize=1024*1024;
       var response= await Client.GetAsync(new Uri(The URL here));
       var result = await response.Content.ReadAsStringAsync();

       var component=JsonObject.Parse(result);

    }
</code></pre>

<p>I need to poll server for every 30 seconds to check for updates and retrieve the JSON. Any suggestions?</p>
