HttpWebRequest / HttpWebResponse Обеспечивает асинхронный кросс-доменный доступ к сетевым ресурсам Позволяет получить контроль над сообщением HTTP Очень полезный при обращении к существующим основанным на формах (т.e. HTTP-POST) ресурсах, которые активно используются в таких технологиях как PHP http://www.remix.ru

Разработка для HTTP Post Uri uri = new Uri("http://localhost:8002/Sample2Web/GetData.ashx"); HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(uri); request.Method = "POST"; request.ContentType = "application/x-www-form-urlencoded"; request.BeginGetRequestStream(new AsyncCallback(RequestProceed), request); void RequestProceed(IAsyncResult asyncResult) { … } void ResponseProceed(IAsyncResult asyncResult) { … }

Подписка на SOAP Web Services Веб-сервисы должны предоставлять файл WSDL и сервер должен иметь crossdomain.xml или clientaccesspolicy.xml, правильно настроенный и расположенный Использование Visual Studio для создания прокси сервиса (основано на HttpWebReq/Resp) Silverlight использует этот прокси асинхронно

Поддержка сокетов В Silverlight возможно сетевое взаимодействие на базе сокетов Ограничения Поддерживаются только порты из диапазона 4502-4534 Коммуникация возможна только с тем же доменом, на котором находится элемент управления Необходим полиси-сервер, расположенный на порту 943 До инициализации соединения Silverlight опрашивает порт 943 для получения информации о полиси, которая содержит разрешенные порты и протоколы
