下面是我的WCF configuratio但是当我尝试添加服务引用

Here is my WCF configuratio but when i try to add service reference to

net.tcp://127.0.0.1:8731/IMSSDirectoryService

我得到一个错误：

I get an error:

元数据包含了一个参考无法得到解决：的net.tcp：//本地主机：8731 / IMSSDirectoryService。

Metadata contains a reference that cannot be resolved: 'net.tcp://localhost:8731/IMSSDirectoryService'.

如果该服务在当前的解决方案定义，尝试构建解决方案，并再次添加服务引用。请帮助我理解我的问题。

If the service is defined in the current solution, try building the solution and adding the service reference again. Please help me to understand my problem.

推荐答案

您有两个相同的基地址定义的：

You have two identical base addresses defined:

<service name="SUR.Core.Service.Implementation.SURDirectoryService" 
         behaviorConfiguration="DefaultServiceBehavior">
  <host>
    <baseAddresses>
      <add baseAddress="net.tcp://127.0.0.1:8731/ISURDirectoryService"/>
    </baseAddresses>


<service name="MSS.Core.Service.Implementation.MSSDirectoryService" 
         behaviorConfiguration="DefaultServiceBehavior">
   <host>
     <baseAddresses>
       <add baseAddress="net.tcp://127.0.0.1:8731/IMSSDirectoryService"   />

这是你的问题的原因 - 连接到时的net.tcp：//127.0.0.1：8731 / ，WCF不知道哪个服务你的意思。

That is the cause of your problems - when connecting to net.tcp://127.0.0.1:8731/, WCF doesn't know which service you mean.

该基址必须在它的架构UNIQUE（如HTTP，等的net.tcp。）

The base address must be UNIQUE within its "schema" (e.g. http, net.tcp etc.)

编辑：如果您希望能够检索使用浏览器和导航到一个URL来得到它的元数据，你需要激活＆LT; serviceMetadata httpGetEnabled =真/＆GT ; 在服务的行为选择。否则，你将只能得到在使用超过一个的net.tcp SOAP调用你的元数据 - 如：使用WcfTestClient.exe应用程序，它是在你的Visual Studio 9 / Common7 / IDE文件夹。

if you want to be able to retrieve your metadata using the browser and navigating to a URL to get it, you'll need to activate the <serviceMetadata httpGetEnabled="True"/> in your service behavior option. Otherwise, you'll only be able to get at your metadata using a SOAP call over net.tcp - e.g. using the "WcfTestClient.exe" app which is in your Visual Studio 9/Common7/IDE folder.

编辑2：您已经定义了一些额外的绑定和行为的墨西哥，但因为没有你的MEX终结点实际上是引用任何这些设置，他们没有被使用

EDIT 2: you have defined a number of extra bindings and behaviors for MEX, but since none of your mex endpoints is actually referencing any of those settings, they're not being used.
