【问题描述】：

你能帮我解决我的错误吗？

我在 WinForm 程序集中自行托管 WCF，我正在尝试生成客户端 app.config 和服务接口。我在 VS2015 开发者命令提示符下执行 svcutil http://localhost:8880/MyOwnWCFService/ /Language=c# /t:Code /out:C:\Service\ServiceProxy.cs /config:C:\Service\ServiceProxy.config 。

我收到以下错误：

错误：无法从http://localhost:8880/MyOwnWCFService/获取元数据

如果这是您有权访问的 Windows (R) Communication Foundation 服务，请检查您是否已在指定地址启用元数据发布。如需启用元数据发布的帮助，请参阅位于 http://go.microsoft.com/fwlink/?LinkId=65455 的 MSDN 文档。

WS-元数据交换错误 网址：http://localhost:8880/MyOwnWCFService/

Metadata contains a reference that cannot be resolved: 'http://localhost:8880/MyOwnWCFService/'.

Content Type application/soap+xml; charset=utf-8 was not supported by service http://localhost:8880/MyOwnWCFService/.  The client and service bindings may be mismatched.

The remote server returned an error: (415) Cannot process the message because the content type 'application/soap+xml; charset=utf-8' was not the expected type 'text/xml; charset=utf-8'..

HTTP GET 错误 网址：http://localhost:8880/MyOwnWCFService/

There was an error downloading 'http://localhost:8880/MyOwnWCFService/'.

请求失败并显示错误消息：

由于内部错误，服务器无法处理请求。有关该错误的更多信息，请在服务器上打开 IncludeExceptionDetailInFaults（来自 ServiceBehaviorAttribute 或来自配置行为）以便将异常信息发送回客户端，或者根据 Microsoft .NET Framework SDK 文档打开跟踪并检查服务器跟踪日志。 --.

如果您需要更多帮助，请输入“svcutil /?”

我的自托管代码：

System.ServiceModel.Channels.Binding MexHttpBinding = MetadataExchangeBindings.CreateMexHttpBinding();

               String baseAddress = "http://localhost:8880/MyOwnWCFService/";
                NetTcpBinding tcpbinding = new NetTcpBinding(SecurityMode.None);
                tcpbinding.Name = "SEMSIntegration_NetTcpBinding_iSEMSIntegrationWCFService";
                tcpbinding.OpenTimeout = new TimeSpan(00, 01, 00);
                tcpbinding.CloseTimeout = new TimeSpan(00, 01, 00);
                tcpbinding.ReceiveTimeout = new TimeSpan(00, 01, 00);
                tcpbinding.SendTimeout = new TimeSpan(00, 01, 00);
                tcpbinding.TransactionFlow = false;
                tcpbinding.TransferMode = TransferMode.Buffered;
                tcpbinding.TransactionProtocol = TransactionProtocol.OleTransactions;
                tcpbinding.HostNameComparisonMode = HostNameComparisonMode.StrongWildcard;
                tcpbinding.ListenBacklog = 10;
                tcpbinding.MaxBufferPoolSize = 524288;
                tcpbinding.MaxBufferSize = 524288;
                tcpbinding.MaxConnections = 100;
                tcpbinding.MaxReceivedMessageSize = 524288;

                WindowState = FormWindowState.Minimized;
                SEMSService = new MyOwnWCFService();
                SEMSHost = new ServiceHost(SEMSService, new Uri(baseAddress));

                ServiceMetadataBehavior smb = SEMSHost.Description.Behaviors.Find<ServiceMetadataBehavior>();
                // If not, add one
                if (smb == null)
                
                    smb = new ServiceMetadataBehavior();
                
                smb.HttpGetEnabled = true;
                smb.MetadataExporter.PolicyVersion = PolicyVersion.Policy15;
                SEMSHost.Description.Behaviors.Add(smb);
                SEMSHost.Description.Behaviors.Add(new ServiceDiscoveryBehavior());

                SEMSHost.AddServiceEndpoint(new UdpDiscoveryEndpoint());
                SEMSHost.AddServiceEndpoint(typeof(iSEMSIntegrationWCFService), new BasicHttpBinding(), "http://localhost:8880/MyOwnWCFService");
                SEMSHost.AddServiceEndpoint(typeof(iSEMSIntegrationWCFService), tcpbinding, "net.tcp://localhost:8888/MyOwnWCFService");
                SEMSHost.AddServiceEndpoint("IMetadataExchange", MexHttpBinding, "mex");

                SEMSHost.Open();

【问题讨论】：

我的 WCF 知识有点生疏。如果将 svcutil 命令行更改为 http://localhost:8880/MyOwnWCFService/wsdl? 会发生什么？

我几乎得到了同样的错误（太长，无法添加到此评论中）。

This is because you are getting the error:

System.Runtime.Serialization.InvalidDataContractException: Type 'System.Windows.Forms.Menu' cannot be serialized.

See browser exception detail:

An ExceptionDetail, likely created by IncludeExceptionDetailInFaults=true, whose value is:
System.InvalidOperationException: An exception was thrown in a call to a WSDL export extension: System.ServiceModel.Description.DataContractSerializerOperationBehavior
 contract: http://tempuri.org/:iSEMSIntegrationWCFService ----> System.Runtime.Serialization.InvalidDataContractException: Type 'System.Windows.Forms.Menu' cannot be serialized. Consider marking it with the DataContractAttribute attribute, and marking all of its members you want serialized with the DataMemberAttribute attribute.  If the type is a collection, consider marking it with the CollectionDataContractAttribute.  See the Microsoft .NET Framework documentation for other supported types.
