.net 使用Mex时出现问题

我的应用程序同时使用NetTcpBinding和BasicHttpBinding，但它们都将公开我的服务类的一个子集。我已经创建了如下服务

问题是，尽管我刚刚将3个合同添加到Mex绑定中，但当我想将服务添加到项目中时，所有合同都会显示出来

m_ServiceHost = new ServiceHost(typeof(Services), baseAddresses); 

BasicHttpBinding basicHttpBinding = new BasicHttpBinding(); 
basicHttpBinding.UseDefaultWebProxy = false; 

m_ServiceHost.AddServiceEndpoint(typeof( IMyFirstService), basicHttpBinding, "MyFirstService"); 
m_ServiceHost.AddServiceEndpoint(typeof(IMySecondService), basicHttpBinding, "MySecondService"); 
m_ServiceHost.AddServiceEndpoint(typeof(IMyThirdService), basicHttpBinding, "MyThirdService"); 

NetTcpBinding netTcpBinding = new NetTcpBinding(); 
netTcpBinding.MaxReceivedMessageSize = 2147483647; 
netTcpBinding.ReaderQuotas.MaxNameTableCharCount = 2147483647; 

m_ServiceHost.AddServiceEndpoint(typeof(IMyFirstService), netTcpBinding, "MyFirstService"); 
m_ServiceHost.AddServiceEndpoint(typeof(IMySecondService), netTcpBinding, "MySecondService"); 
m_ServiceHost.AddServiceEndpoint(typeof(IMyFourthService), netTcpBinding, "MyFourthService"); 
m_ServiceHost.AddServiceEndpoint(typeof(IMyFifthService), netTcpBinding, "MyFifthService"); 
m_ServiceHost.AddServiceEndpoint(typeof(IMySixService), netTcpBinding, "MySixService"); 


HttpTransportBindingElement httpTransport = new HttpTransportBindingElement(); 
httpTransport.MaxReceivedMessageSize = 2147483647; 
httpTransport.MaxBufferSize = 2147483647; 

TextMessageEncodingBindingElement textMessageEncoding = new TextMessageEncodingBindingElement(); 
textMessageEncoding.ReaderQuotas.MaxDepth = 2147483647; 
textMessageEncoding.ReaderQuotas.MaxStringContentLength = 2147483647; 
textMessageEncoding.ReaderQuotas.MaxArrayLength = 2147483647; 
textMessageEncoding.ReaderQuotas.MaxBytesPerRead = 2147483647; 
textMessageEncoding.ReaderQuotas.MaxNameTableCharCount = 2147483647;               

System.ServiceModel.Channels.CustomBinding mexHttpCustomBinding = new System.ServiceModel.Channels.CustomBinding(textMessageEncoding, httpTransport); 
mexHttpCustomBinding.Name = "MexHttpBindingConfig"; 
               m_ServiceHost.AddServiceEndpoint(typeof(System.ServiceModel.Description.IMetadataExchange), mexHttpCustomBinding, "mex"); 

m_ServiceHost.Open();

我认为实现这一点的唯一方法是创建两个独立的服务主机。一个用于通过http公开的服务，另一个用于通过net.tcp绑定公开的服务

完成了。原始问题只是链接到了。@Adam:做得好。今天早上我太快就失去耐心了。
