WCF代理中的系统命名空间冲突

Question

我正在尝试为我创建的WCf服务生成代理。服务中的一个操作具有返回类型WebHeaderCollection，它恰好是System.Net Assembly的一部分。我正在使用以下命令生成代理。

>svcutil.exe /language:cs /out:Proxies/AuthManagerProxy.cs /ct:System.Collections.Generic.List`1 /config:Proxies/out.config https://localhost/OpenAPISecurityManager/AuthManager.svc /serializer:DataContractSerializer

我面临的问题是Proxy包含根命名空间的定义，这会导致客户端发生冲突。我可以手动删除定义，一切正常，但我不知道这种奇怪行为的原因是什么。如果我使用visual studio添加服务引用，那么我不会遇到问题。

向下滚动下面的代码片段（第112行，我想看看为命名空间生成的代码）
