WCF NetTcpBinding的托管在IIS7.5停止工作 [英] WCF netTcpBinding hosted on IIS7.5 Stops Working

问题描述

我有我已经在IIS7.5本地托管简单的.NET 4 WCF服务。最初，我是有托管使用 httpBinding 这工作得很好。然后我切换到 NetTcpBinding的，它改变了的web.config后相应的文件也工作正常。然而今天，它已决定停止工作。使用测试客户端的所有，让我无法连接到该服务：

URI：的net.tcp：//localhost/case/service.svc/mex元数据包含了一个参考无法得到解决：的net.tcp：//localhost/case/service.svc/ MEX。无法调度的消息，因为在端点地址的服务。的net.tcp：//localhost/case/service.svc/mex'是地址的协议无效

我已经检查了非HTTP激活服务（仍然）安装;净TCP监听服务正在运行;是的net.tcp在为网站启用的协议列表;我已经运行 servicemodelreg.exe -ia ;我也重新运行 ASPNET_REGIIS.EXE -i ;最后我已经检查了net.tcp绑定是在网站上。

如果我跑的netstat 我可以看到一些监听的端口上，但我无法连接到它。

这是我发疯，因为今天早上它工作正常（上周，因为它是），现在它只是没有。

编辑：：如果我进入IE中的服务的话，我可以看到它抛出了以下异常：

 找不到与绑定NetTcpBinding的端点符合计划的net.tcp的基址。已注册的基址方案是[HTTP]。
 

不过看在的web.config 文件似乎并没有这样的情况：

 ＆LT;服务＆GT;
  ＆LT;服务behaviorConfiguration =ServiceBehaviorNAME =[删除] [删除]＆GT;
    ＆LT;端点绑定=NetTcpBinding的bindingConfiguration =PortSharingBinding合同=[删除] [删除]。/＆GT;
    ＆LT;端点地址=MEX绑定=mexTcpBinding合同=IMetadataExchange接口/＆GT;
  ＆LT; /服务＆GT;
＆LT; /服务＆GT;

＆LT;绑定＆GT;
  ＆LT; NetTcpBinding的＆GT;
    ＆LT;绑定名称=PortSharingBindingportSharingEnabled =真正的＆GT;
      ＆LT;安全模式=无/＆GT;
    ＆LT; /装订＆GT;
    ＆LT;绑定名称=mexTcpBindingportSharingEnabled =真正的＆GT;
      ＆LT;安全模式=无/＆GT;
    ＆LT; /装订＆GT;
  ＆LT; / NetTcpBinding的＆GT;
＆LT; /绑定＆GT;
 

解决方案

OK，终于解决了这个问题。我已使协议的net.tcp在网站级别，但它并没有在应用程序级别启用。我想这一定是之前，我想改变项目名称前面会后我创建了一个新的应用程序，显然忘了设置上的应用协议 - 卫生署

因此​​，对于托管在IIS中的WCF服务的net.tcp最终清单是：

1. 确保WCF非HTTP激活服务安装
2. 确保监听器的net.tcp 服务和 Net.Tcp端口共享服务都运行
3. 添加的net.tcp到启用的协议的网站和应用程序（来访问IIS管理器中的高级设置选项，则必须有一个HTTP绑定present）
4. 运行 servicemodelreg.exe -ia 注册WCF元素IIS
5. 运行 ASPNET_REGIIS.EXE -i 来确保.NET是正确设置与IIS
6. 添加net.tcp绑定的网站

I have a simple .NET 4 WCF service which I have hosted locally on IIS7.5. Initially I had it hosted using httpBinding which worked fine. Then I switched it to netTcpBinding, which after changing the web.config file accordingly was also working fine. However today it has decided to stop working. I cannot connect to the service using the test client at all, getting:

URI: net.tcp://localhost/case/service.svc/mex Metadata contains a reference that cannot be resolved: 'net.tcp://localhost/case/service.svc/mex'. The message could not be dispatched because the service at the endpoint address 'net.tcp://localhost/case/service.svc/mex' is unavailable for the protocol of the address.

I have checked that the non-http activation service is (still) installed; the net tcp listener service is running; net.tcp is in the list of enabled protocols for the site; I have run servicemodelreg.exe -ia; I have also re-run aspnet_regiis.exe -i; and finally I have checked the net.tcp binding is on the site.

If I run netstat I can see something is listening on the port, but I cannot connect to it.

This is driving me nuts, as this morning it was working fine (as it was last week) and now it's just not.

EDIT: If I access the service in IE then I can see it's throwing the following exception:

Could not find a base address that matches scheme net.tcp for the endpoint with binding NetTcpBinding. Registered base address schemes are [http].

But looking in the web.config file that doesn't seem to be the case:

<services>
  <service behaviorConfiguration="ServiceBehavior" name="[REMOVED].[REMOVED]">
    <endpoint binding="netTcpBinding" bindingConfiguration="PortSharingBinding" contract="[REMOVED].[REMOVED]" />
    <endpoint address="mex" binding="mexTcpBinding" contract="IMetadataExchange" />
  </service>
</services>

<bindings>
  <netTcpBinding>
    <binding name="PortSharingBinding" portSharingEnabled="true">
      <security mode="None"/>
    </binding>
    <binding name="mexTcpBinding" portSharingEnabled="true">
      <security mode="None" />
    </binding>
  </netTcpBinding>
</bindings>

解决方案

OK, finally solved it. I had enabled net.tcp protocol at the site level, but it was not enabled at the application level. I guess it must have been before, and I think I might of created a new application after changing the project name earlier and obviously forgot to set the protocol on the application - doh!

So the final checklist for hosting a WCF net.tcp service on IIS is:

1. Ensure the WCF Non-HTTP Activation service is installed
2. Ensure the Net.Tcp Listener Service and Net.Tcp Port Sharing Service are both running
3. Add net.tcp to the enabled protocols for the site and the application (to access the Advanced Settings option from IIS Manager you must have an http binding present)
4. Run servicemodelreg.exe -ia to register WCF elements with IIS
5. Run aspnet_regiis.exe -i to ensure .NET is setup correctly with IIS
6. Add net.tcp binding to the site
