How to use Bing Spatial service to get nearby areas and how to add them to our map control

Question

I am using query Api to get the near by locations with in given radius. How to add them to our map control and bind them to a UI control.

public class SpatialDataQuerying
{
   static void Main()
   {
   SpatialDataQuerying queryTest = new SpatialDataQuerying();
   queryTest.RunExampleQueries();      
   }

   public void RunExampleQueries()
   {
      ExampleFindByAreaRadius();   
   }
   public async void ExampleFindByAreaRadius()
     {
      string dataSourceName = "petrolbunk";
      string dataEntityName = "petrolbunk";

      string accessId = DataSourceID;

      string bingMapsKey = BingMapsKey;

      double SearchLatitude = 47.63674;
      double SearchLongitude =  - 122.30413;

      double Radius = 3;      
      string requestUrl = string.Format("http://spatial.virtualearth.net/REST/v1/data/{0}/{1}/{2}" + "?spatialFilter=nearby({3},{4},{5})&key={6}",accessId,dataSourceName,
    dataEntityName,SearchLatitude, SearchLongitude, Radius, bingMapsKey);

As you know after this query the url is sent through HTTP web request.

HttpWebRequest request = WebRequest.Create(requestUrl) as HttpWebRequest;
HttpWebResponse response = await request.GetResponseAsync() as HttpWebResponse;

Now how to store this response to a list and display them in map control. Also how to bind the area to our UI control.
