我的服务托管在 IIS7 上，启用了 net.tcp 协议。当我从 IIS 浏览服务时，我可以看到服务页面及其 tcp 地址，但如果我将该地址用于 WCF 测试客户端或任何应用程序作为服务参考我在 wcf 客户端中出现此错误

Error: Cannot obtain Metadata from http://localhost:808/MyService/MyService.svc?wsdl 
If this is a Windows (R) Communication Foundation service to which you have access, 
please check that you have enabled metadata publishing at the specified address. 
For help enabling metadata publishing, 
 please refer to the MSDN documentation at http://go.microsoft.com/fwlink/?LinkId=65455
WS-Metadata Exchange Error 
URI: http://localhost:808//MyService/MyService.svc?wsdl
 Metadata contains a reference that cannot be resolved:
 'http:/localhost:808/MyService/MyService.svc?wsdl .
 There was no endpoint listening at
'http:/localhost:808/MyService/MyService.svc?wsdl that could accept the message. 
 This is often caused by an incorrect address or SOAP action. See InnerException, 
 if present, for more details.    
The remote server returned an error: (404) Not Found.HTTP GET Error 
URI: http:/localhost:808/MyService/MyService.svc?wsdl    
The HTML document does not contain Web service discovery information.

当我将 net.tcp 地址放入 wcf 客户端时，我很惊讶为什么错误仅与 http 有关

我的服务配置是

由于是 netTcp Binding，所以不能在 wcf 测试客户端中添加并测试。要在 WCF 测试客户端中使用，您还需要使用 Http 公开服务（即，同时使用 Http 和 NetTcp 绑定）。然后您可以浏览元数据并使用 Http 在 wcf 测试客户端中使用它。使用 NetTcp 绑定向客户端公开服务。希望我已经回答了你的问题。

注意：在您托管的网站下的 IIS 中，转到高级设置并将允许的绑定提及为“Http,NetTcp”。

我找到了根本原因，因为从 Windows 功能激活 WCF 非 http 激活存在一些问题，它总是给出诸如操作无法完成之类的错误。我能够在其他机器上运行我的服务，但仍然想知道可能是什么WCF非http激活错误的可能原因。
