• Create rich Search apps • Live Search 2.0 publishes a crossdomain.xml policy file – http://api.search.live.net/crossdomain.xml – Allows Search 2.0 API from Silverlight

• APIs are the same as .NET – HTTP XML or SOAP

• Also has a JSON parsing object model • APIs are asynchronous

Silverlight Sample Setup callback and make query WebClient wc = new WebClient(); wc.OpenReadCompleted += new OpenReadCompletedEventHandler(wc_OpenReadCompleted); item.CurrentQuery = p; item.Uri = new Uri(String.Format(_baseURI, API_KEY, "image", "sushi")); wc.OpenReadAsync(item.Uri, item); WebClient callback void wc_OpenReadCompleted(object sender, OpenReadCompletedEventArgs e) {

Stream streamResult = e.Result;

XDocument xd = XDocument.Load(XmlReader.Create(streamResult));

// use the Xdocument }
