我想添加一个客户端是基于的net.tcp的WCF服务。当我使用添加服务引用，并提供该网址：的net.tcp：//localhost/service1.svc ，它提供了以下错误

的URI preFIX无法识别。元数据包含一个引用   无法解析：'的net.tcp：//localhost/service1.svc。不能   连接到的net.tcp：//localhost/service1.svc。连接尝试   历时00一个时间跨度：00：02.0051147。 TCP错误code 10061：无   连接可以作出，因为目标机器积极地拒绝   它127.0.0.1:808。无连接可以作出，因为目标   计算机主动拒绝127.0.0.1:808如果该服务被定义   当前的解决方案，尝试建立溶液和添加服务   再次参考

我检查了Windows组件的WCF非HTTP服务，但他们都已经安装。这是捕捉：

正如你可以看到，他们安装的.NET 3.5.1和我的服务是建立在.NET 4.5。这是什么问题？而且我应该如何解决呢？因为在Windows组件列表中没有的选择.NET 4.5。

以下是我的WCF服务的配置：

解决方案

这似乎不WCF的HTTP或者非HTTP激活功能和服务之间的不兼容问题。

据对我来说，有一个丢失或错误配置在IIS中，这会解释拒绝连接。要正确配置IIS与的net.tcp ，一看的这里。

I am trying to add a client for a WCF service that is net.tcp based. When I use "Add Service Reference" and provide this URL:net.tcp://localhost/service1.svc, it gives following error.

The URI prefix is not recognized. Metadata contains a reference that cannot be resolved: 'net.tcp://localhost/service1.svc'. Could not connect to net.tcp://localhost/service1.svc. The connection attempt lasted for a time span of 00:00:02.0051147. TCP error code 10061: No connection could be made because the target machine actively refused it 127.0.0.1:808. No connection could be made because the target machine actively refused it 127.0.0.1:808 If the service is defined in the current solution, try building the solution and adding the service reference again.

I checked Windows Components for WCF non-http services, but they are already installed. This is the snap:

As you can see they are installed for .NET 3.5.1 and my service is built in .NET 4.5. Is this the problem? And how should I solve it? Because there is no option for .NET 4.5 in Windows Components List.

Following is the configuration of my WCF service:

<system.serviceModel>
<services>
<service name="CoreService.Service1" behaviorConfiguration="beh1">
  <host>
    <baseAddresses>
      <add baseAddress="net.tcp://localhost/Service1.svc"/>
    </baseAddresses>
  </host>
        <endpoint
     binding="netTcpBinding"
     bindingConfiguration="ultra"
     contract="CoreService.IAccountService"/>
       <endpoint
     binding="netTcpBinding"
     bindingConfiguration="ultra"
     contract="CoreService.ICategoryService"/>
         <endpoint
     binding="netTcpBinding"
     bindingConfiguration="ultra"
     contract="CoreService.ICommonService"/>
         <endpoint
     binding="netTcpBinding"
     bindingConfiguration="ultra"
     contract="CoreService.IFollowerService"/>
         <endpoint
     binding="netTcpBinding"
     bindingConfiguration="ultra"
     contract="CoreService.IInterestService"/>
<endpoint
     binding="netTcpBinding"
     bindingConfiguration="ultra"
     contract="CoreService.IInviteService"/>

  <endpoint
          address="mex"
          binding="mexTcpBinding"
          contract="IMetadataExchange"/>
</service>
</services>
<bindings>
<netTcpBinding>
<binding name="ultra"
     maxBufferPoolSize="2147483647"
     maxBufferSize="2147483647"
     maxConnections="2147483647"
     maxReceivedMessageSize="2147483647"
     portSharingEnabled="false"
     transactionFlow="false"
     listenBacklog="2147483647"
     sendTimeout="00:01:00">
<security mode="None">
<message clientCredentialType="None"/>
<transport protectionLevel="None" clientCredentialType="None"/>
</security>
<reliableSession enabled="false"/>
</binding>
</netTcpBinding>
</bindings>
<behaviors>
    <serviceBehaviors>
      <behavior name="beh1">
        <serviceMetadata httpGetEnabled="true" />
        <serviceDebug includeExceptionDetailInFaults="True" />
        <dataContractSerializer maxItemsInObjectGraph="65536" />
      </behavior>
    </serviceBehaviors>
  </behaviors>
</system.serviceModel>

It doesn't seem an incompatibility issue between the WCF HTTP or Non-HTTP Activation features and your service.

According to me, there's a missing or wrong configuration in IIS and that would explain the refused connection. To configure properly IIS with with net.tcp, have a look here.
