将mex端点添加到NetNamedPipeBinding

我正在尝试通过NetNamedPipeBinding公开接口。

这就是我的所作所为:

        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项目并尝试在位置net.pipe://localhost/myservice/添加服务引用时,我收到以下错误:

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.

如果我将NetNamedPipeBinding替换为TcpBinding,则代码可以正常工作,并且可以添加服务引用。

我应该更改什么,以便在Visual Studio中添加服务引用?

var netNamedPipeLocation = "net.pipe://localhost/myservice/"; netNamedPipeLocation + "/mex"结束net.pipe://localhost/myservice//mex。您的AddServiceEndPoint电话应为

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

删除额外/我之后能够连接到使用您的代码托管的本地命名管道服务而没有问题。
