I am running heavy WCF RIA service operation and getting such error on client-side Silverlight app:

    Uncaught Error: Unhandled Error occurred in Silverlight Application:
Submit operation failed. Для запроса HTTP к 

"https://localhost/MyProject/ClientBin/myservice.svc/binary" has exceeded the allotted timeout. The time allotted to this operation may have been a portion of a longer timeout.


Stack Trace:
   в System.Windows.Ria.OperationBase.Complete(Exception error)
   в System.Windows.Ria.SubmitOperation.Complete(Exception error)
   в System.Windows.Ria.DomainContext.CompleteSubmitChanges(IAsyncResult asyncResult)
   в System.Windows.Ria.DomainContext.<>c__DisplayClassd.<SubmitChanges>b__5(Object )

I am getting such timeout in 1 minute of execution.

My context looks like that:

[EnableClientAccess()]
public class ConfigService : LinqToEntitiesDomainService<MyEntityFrameworkEntities>

Here is code screenshot:

本主题中讨论的所有设置都是在绑定本身上进行的，无论是在代码中还是在配置中。以下代码显示如何在自承载服务的上下文中以编程方式设置 WCF 绑定的超时。

public static void Main()
            {
                Uri baseAddress = new Uri("http://localhost/MyServer/MyService");

                try
                {
                    ServiceHost serviceHost = new ServiceHost(typeof(CalculatorService));

                    WSHttpBinding binding = new WSHttpBinding();
                    binding.OpenTimeout = new TimeSpan(0, 10, 0);
                    binding.CloseTimeout = new TimeSpan(0, 10, 0);
                    binding.SendTimeout = new TimeSpan(0, 10, 0);
                    binding.ReceiveTimeout = new TimeSpan(0, 10, 0);

                    serviceHost.AddServiceEndpoint("ICalculator", binding, baseAddress);
                    serviceHost.Open();

                    // The service can now be accessed.
                    Console.WriteLine("The service is ready.");
                    Console.WriteLine("Press <ENTER> to terminate service.");
                    Console.WriteLine();
                    Console.ReadLine();

                }
                catch (CommunicationException ex)
                {
                    // Handle exception ...
                }
            }

以下示例显示如何在配置文件中的绑定上配置超时。

<configuration>
  <system.serviceModel>
    <bindings>
      <wsHttpBinding>
        <binding openTimeout="00:10:00" 
                 closeTimeout="00:10:00" 
                 sendTimeout="00:10:00" 
                 receiveTimeout="00:10:00">
        </binding>
      </wsHttpBinding>
    </bindings>
  </system.serviceModel>

你应该编辑 RIA 服务

域上下文创建后的任一行：

((WebDomainClient<LibraryDomainContext.ILibraryDomainServiceContract>)this.DomainClient).ChannelFactory.Endpoint.Binding.SendTimeout = new TimeSpan(0, 5, 0);

或部分课程

public partial class LibraryDomainContext
{
   partial void OnCreated()
   {
      if(DesignerProperties.GetIsInDesignMode(App.Current.RootVisual))
         ((WebDomainClient<LibraryDomainContext.ILibraryDomainServiceContract>)this.DomainClient).ChannelFactory.Endpoint.Binding.SendTimeout = new TimeSpan(0, 5, 0);
   }
}

从客户端调用时，您希望增加sendTimeout属性。

closeTimeout = 连接关闭的时间间隔

openTimeout = 连接打开的时间间隔

receiveTimeout = 服务允许连接处于非活动状态的时间间隔

sendTimeout = 客户端等待响应的时间间隔
