[英]Silverlight - using duplex with PollingDuplexHttpBinding instead of NetTcpBinding
[英]WCF >> DUPLEX >> SILVERLIGHT >> pollingDuplexHttpBinding = VERY SLOW ! BIG DELAY
我有
具有wSDualHttpBinding綁定的WCF用於WPF應用->效果很好! 讓WCF立即發布方法。
在wpf應用程序得到它之后,另一個與pollingDuplexHttpBinding綁定的silvelight 4->非常慢-> 30 ++-秒的延遲(WPF立即得到它)
這是為什么 ? 最好的google結果是
我真的不知道該怎么做...

步驟一:從服務中刪除AspNetCompatibilityRequirements
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class Service1 : IService1
至
public class Service1 : IService1
如果從Web.config進行設置,則將其刪除。
第二步:在Silverlight中使用客戶端堆棧
private void Application_Startup(object sender, StartupEventArgs e)
{
WebRequest.RegisterPrefix("http://", WebRequestCreator.ClientHttp);
WebRequest.RegisterPrefix("https://", WebRequestCreator.ClientHttp);
}
