how to use http client in windows 8 app

i made an app in windows phone successfully & now i want to make it for windows 8 store app but i stuck on a point where i want to my web service in store app.

I use webclient in WP but i don't know anything about how to access web service in Windows 8 store app. My web service return data in json format i deserialize & store in a variable in WP & i use post method . but how it would be done in Windows 8 store app. what would i use for windows 8 in place of Webclient.

i post my windows phone code

 private void PostData()

     Uri uri = new Uri(my web service url);

     string data = "device_id=" + val + "&quiz_type=all";

       WebClient wc = new WebClient();

        wc.Headers[HttpRequestHeader.ContentType] = "application/x-www-form-urlencoded";

        wc.UploadStringAsync(uri, data);

        wc.UploadStringCompleted += wc_UploadComplete;

 public void wc_UploadComplete(object sender, UploadStringCompletedEventArgs e)

var rootObject = JsonConvert.DeserializeObject(e.Result);

You see that i store all the data in rootObject. How these thing can be done in windows 8 app?

Try this out:

var client = new HttpClient();
string data = "device_id=" + val + "&quiz_type=all";

var postContent = new StringContent(data, Encoding.UTF8, "application/x-www-form-urlencoded");

// send request asynchronously and continue when complete
var response = await client.PostAsync(address, postContent);

// check that response was successful or throw exception response.EnsureSuccessStatusCode();

//Read the JSON response
var content = await response.Content.ReadAsStringAsync();
