C# 长期运行的WCF RIA服务调用出现错误404

我们有一个RIA服务调用，它只传递几个参数，但是它可能需要较长的时间来处理（例如20多分钟），当它到达10到15分钟左右时，我们会得到一个错误404 Not Found exception。以下是我们迄今为止为解决超时问题所做的工作： 网络配置-服务器端

<system.serviceModel>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true"/>
<bindings>
  <basicHttpBinding>
    <binding name="" closeTimeout="01:00:00" openTimeout="01:00:00"
    receiveTimeout="01:00:00" sendTimeout="01:00:00" maxBufferSize="2147483647"

两者似乎都没有影响到这个问题。欢迎任何意见

您是否更改了IIS中的超时？是的，没有运气。我们最终找到了一个投票解决方案。

public static class DomainContextExtensions
{
    public static void ChangeWcfTimeouts(this DomainContext context)
    {
        PropertyInfo channelFactoryProperty =
          context.DomainClient.GetType().GetProperty("ChannelFactory");
        if (channelFactoryProperty == null)
        {
            throw new InvalidOperationException(
              "There is no 'ChannelFactory' property on the DomainClient.");
        }
        TimeSpan timeout = new TimeSpan(1, 0, 0); // 1 Hour

        ChannelFactory factory = (ChannelFactory)channelFactoryProperty.GetValue(context.DomainClient, null);
        factory.Endpoint.Binding.SendTimeout = timeout;
        factory.Endpoint.Binding.CloseTimeout = timeout;
        factory.Endpoint.Binding.OpenTimeout = timeout;
        factory.Endpoint.Binding.ReceiveTimeout = timeout;
    }
}
