我正在尝试通过 NetNamedPipeBinding 公开一个接口。

这就是我所做的：

        try
        {
            //load the shedluer static constructor
            ServiceHost svh = new ServiceHost(typeof(MyClass));

            var netNamedPipeBinding = new NetNamedPipeBinding(NetNamedPipeSecurityMode.None);

            var netNamedPipeLocation = "net.pipe://localhost/myservice/";
            svh.AddServiceEndpoint(typeof(IMyInterface), netNamedPipeBinding, netNamedPipeLocation);

            // Check to see if the service host already has a ServiceMetadataBehavior
            ServiceMetadataBehavior smb = svh.Description.Behaviors.Find<ServiceMetadataBehavior>();
            // If not, add one
            if (smb == null)
                smb = new ServiceMetadataBehavior();

            smb.MetadataExporter.PolicyVersion = PolicyVersion.Policy15;
            svh.Description.Behaviors.Add(smb);

            // Add MEX endpoint
            svh.AddServiceEndpoint(
                ServiceMetadataBehavior.MexContractName,
                MetadataExchangeBindings.CreateMexNamedPipeBinding(),
                netNamedPipeLocation + "/mex"
                );

            svh.Open();

            Console.WriteLine("Service mounted at {0}", netNamedPipeLocation);
            Console.WriteLine("Press ctrl+c to exit");

            ManualResetEvent me=new ManualResetEvent(false);
            me.WaitOne();
            svh.Close();
        }
        catch (Exception e)
        {
            Console.WriteLine("Exception");
            Console.WriteLine(e);
        }

服务启动正常，但是当我创建一个新的 Visual Studio 项目并尝试在 location 添加服务引用时net.pipe://localhost/myservice/，出现以下错误：

The URI prefix is not recognized.
Metadata contains a reference that cannot be resolved: 'net.pipe://localhost/myservice/'.
Metadata contains a reference that cannot be resolved: 'net.pipe://localhost/myservice/'.
If the service is defined in the current solution, try building the solution and adding the service reference again.

如果我用 NetNamedPipeBinding 代替 TcpBinding，代码可以正常工作，并且可以添加服务引用。

我应该更改什么，以便可以在 Visual Studio 中添加服务引用？

随着var netNamedPipeLocation = "net.pipe://localhost/myservice/"; netNamedPipeLocation + "/mex"风起云涌net.pipe://localhost/myservice//mex。你的AddServiceEndPoint电话应该是

svh.AddServiceEndpoint(
            ServiceMetadataBehavior.MexContractName,
            MetadataExchangeBindings.CreateMexNamedPipeBinding(),
            netNamedPipeLocation + "mex"
            );

删除额外的 / 后，我能够毫无问题地连接到使用您的代码托管的本地命名管道服务。
