Silverlight WCF 抛出远程服务器返回错误：NotFound

Question

我试图弄清楚为什么会发生这种情况。超级诡异的

以下是我的确切电话。每当我在车辆数据合同末尾添加那个额外的数据成员时，我都会得到远程服务器返回一个错误：NotFound。当调用 pick.SaveVehiclesAsync(infoKey, data);

从 Silverlight 一侧

public void SaveVehicles(InfoKey infoKey, ObservableCollection<VehicleFullInfoModel> vehicleFullInfoCollection, EventHandler<SaveVehiclesEventArgs> callBack)
    {
        var pick = new **ProjectServiceClient**();
        pick.SaveVehiclesCompleted += (sender, e) =>
        {
            if (callBack != null)
                callBack(this, new SaveVehiclesEventArgs(e.Result, e.fault));
        };
        var data =
            new ObservableCollection<VehicleFullInfo>(vehicleFullInfoCollection.Select(rec => rec.Data).ToList());
        pick.SaveVehiclesAsync(infoKey, data);
    }

----------来自 WCF 服务

public interface IProjectService
{
    [OperationContract]
    string SaveVehicles(InfoKey infoKey, IList<VehicleFullInfo> vehicleFullInfoCollection, out FaultContract fault);
}
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class ProjectService : IProjectService
{
    public string SaveVehicles(InfoKey infoKey, IList<VehicleFullInfo> vehicleFullInfoCollection, out FaultContract fault)
    {      
        return PickVehicles.SaveVehicles(infoKey, vehicleFullInfoCollection,  out fault);
    }
}

Answer 1

Not Found 是 Silverlight 上的一般错误，这可能意味着很多事情 - 跨域问题、来自网络的任何非 200 响应等。您可以做一些事情，例如启用跟踪服务器端，或使用 Fiddler 等工具查看网络流量，这将为您提供有关错误的更多信息。

大多数情况下会发生此错误，只需右键单击每次在时钟附近运行应用程序时打开的 ASP.NET IIS 服务器图标并停止它。

然后再试一次。

Answer 3

尝试在服务器配置文件的终点设置绑定配置 - 示例：

 <endpoint
           address=""
           binding="pollingDuplexHttpBinding"
           bindingConfiguration="multipleMessagesPerPollPollingDuplexHttpBinding"
           contract="DuplexService.IDuplexService">
</endpoint>

但当然您必须配置相应的绑定 - 例如：

<bindings>
        <pollingDuplexHttpBinding>
          <binding name="multipleMessagesPerPollPollingDuplexHttpBinding"
                   duplexMode="MultipleMessagesPerPoll"
                   maxOutputDelay="00:00:07"/>
        </pollingDuplexHttpBinding>
</bindings>

祝你好运。

Make sure your wcf has tracing enabled。 这通常是导致我遇到问题的原因，这次也是。
