问题：

基础连接已关闭：连接意外关闭。这发生在我的 WCF 服务上，该服务托管在 Visual Studio 2010 内置开发服务器上。

信息：

这不会一直发生我认为这是一个“大数据”问题，我已经尽我所能用谷歌搜索，但我实施的解决方案都没有解决任何问题（我已经尝试了其中的大部分）我最可能只是错过了一些愚蠢的东西。

问题：

为什么会发生这种情况，我该如何解决？

WCF 活动日志错误消息：

尝试序列化参数 http://tempuri.org/:ScenarioSummaryResult时出错。The InnerException message was 'Type 'System.Data.Entity.DynamicProxies.ScenarioSummary_A170028D0330F7804BAB85D00BA1EB45FA1754C8A6F6E98C0F003F15078E23A9' with data contract name 'ScenarioSummary_A170028D0330F7804BAB85D00BA1EB45FA1754C8A6F6E98C0F003F15078E23A9: http://schemas.datacontract.org/2004/07/System.Data.Entity.DynamicProxies ' is not expected. 考虑使用 DataContractResolver 或将任何静态未知的类型添加到已知类型列表中 - 例如，通过使用 KnownTypeAttribute 属性或将它们添加到传递给 DataContractSerializer 的已知类型列表中。有关更多详细信息，请参阅 InnerException。

服务信息：

我正在尝试返回实体框架内容的列表

//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：

对于我在这件事上明显无能以及如何纠正它的任何帮助/解释将不胜感激。

有人评论说我的错误看起来很像What are the downsides to turn off ProxyCreationEnabled for CTP5 of EF code first

这实际上是我的解决方案。他们已经删除了他们的帖子。谢谢你比我更擅长谷歌搜索的神秘陌生人。
