底层连接已关闭：连接意外关闭

底层连接已关闭：连接意外关闭。这发生在托管在开发服务器中构建的Visual Studio 2010的我的WCF服务上。

信息：

这种情况不会发生，我相信这是一个“大数据”的问题所有的时间，我用Google搜索硬如我可以，但我已经实现了固定的任何解决方案的非（和我已经尝试了其中的大部分）我最有可能只是失去了一些愚蠢的东西。

问：

这究竟是为什么以及如何解决呢？

客户端的app.config：

WCF活动日志埃罗消息：

而试图序列参数时出错http://tempuri.org/:ScenarioSummaryResult。该消息的InnerException是 “类型 ‘System.Data.Entity.DynamicProxies.ScenarioSummary_A170028D0330F7804BAB85D00BA1EB45FA1754C8A6F6E98C0F003F15078E23A9’ 数据合同名称 ‘ScenarioSummary_A170028D0330F7804BAB85D00BA1EB45FA1754C8A6F6E98C0F003F15078E23A9：http://schemas.datacontract.org/2004/07/System.Data.Entity.DynamicProxies’ 预计不会。考虑使用DataContractResolver或将任何未知的类型静态添加到已知类型的列表中 - 例如，使用KnownTypeAttribute属性的或将其添加到传递给DataContractSerializer的已知类型的列表中。有关更多详细信息，请参阅 InnerException。

服务信息：

我试图返回的实体框架的完整清单

//IService1.cs 
[OperationContract] 
List<ProgramService.ScenarioSummary> ScenarioSummary(string Module); 

//Service1.svc 
public List<ProgramService.ScenarioSummary> ScenarioSummary(string module) 
     { 
      return (from p in Entity.ScenarioSummaries where p.ModuleId.Equals(Entity.Modules.FirstOrDefault(q => q.ModuleName.Equals(module)).Id) select p).ToList(); 
     }

附加信息：

在这件事上我清楚无能的任何帮助/解释，如何纠正它将不胜感激。

您是否尝试过增加绑定conf中的超时时间？像' ...'。只是为了确保，不是这种超时是问题的原因。 – Desty
