Question

我有一个WCF服务，如果我在其中创建代理的项目（通过添加服务引用）与WCF服务在相同解决方案中，我可以为它创建代理

但是，如果我尝试在项目中添加服务引用，该项目与WCF服务（我确实运行）的解决方案不同，则无法找到端点。

有关元数据的消息说明，但我添加了以下暴露元数据的行为

<serviceMetadata httpGetEnabled="true" />

错误消息的详细信息如下：

There was an error downloading 'http://localhost:8112/LTA/_vti_bin/ListData.svc/$metadata'.
The request failed with HTTP status 405: Method Not Allowed.
Metadata contains a reference that cannot be resolved: 'http://localhost:8112/LTA'.
There was no endpoint listening at http://localhost:8112/LTA 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.
If the service is defined in the current solution, try building the solution and adding the service reference again.

有谁知道问题是什么？整个ServiceModel元素是：

<system.serviceModel>
<services>
  <service name="WCFLicenceService.LicenceTrackerService">
    <host>
      <baseAddresses>
        <add baseAddress="http://localhost:8112" />
      </baseAddresses>
    </host>
    <endpoint address="LTS" binding="basicHttpBinding" contract="WCFLicenceService.ILicenceTrackerService" />
    <endpoint 
      address="net.tcp://localhost:8113/LTS" 
      binding ="netTcpBinding" 
      contract="WCFLicenceService.ILicenceTrackerService" />
  </service>
</services>

    </binding>

    <binding maxReceivedMessageSize="2147483647" maxBufferSize="2147483647">
      <readerQuotas maxArrayLength="2147483647" maxStringContentLength="2147483647"/>
    </binding>
  </netTcpBinding>
</bindings>
</system.serviceModel>

正如您所见，服务引用是针对必须存在的http://localhost:8112/LTA/_vti_bin/ListData.svc/$metadata创建的。如果Web服务项目位于同一个Sln中，VS IDE可以通过在内置Web服务器（如IIS Express）上启动服务来为您执行技巧。如果服务项目位于另一个sln中，则必须在另一个VS IDE实例中运行该服务。

对于大型项目，以及其他VS解决方案中的许多其他项目所使用的Web服务，最好不要使用服务引用方法，而是可以为每个服务创建客户端API。客户端API可以分发给其他.NET项目。有关如何创建客户端API和各自优势的更多详细信息，请检查 WCF for the Real World, Not Hello World

WCF仅在同一项目中添加服务引用
