【问题描述】：

尝试使用 WCF service 时出现以下错误。 I looked into this issue and both name and contract values are same in both config files.

找不到名为“BasicHttpBinding_IService1”的端点元素并在 ServiceModel 客户端中签订合同“ServiceReference1.IService1” 配置部分。这可能是因为没有配置文件为您的应用程序找到，或者因为没有匹配的端点元素此名称可以在客户端元素中找到。

WCF 服务是我的解决方案中的类库，我正在尝试在同一解决方案下的另一个类库项目中使用它。

客户端配置

  <endpoint address="http://localhost:8733/Design_Time_Addresses/WcfServiceLibrary1/Service1/"
    binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IService1"
    contract="ServiceReference1.IService1" name="BasicHttpBinding_IService1" />
</client>

WCF 配置文件

<configuration>

  <appSettings>
    <add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />
  </appSettings>
  <system.web>
    <compilation debug="true" />
  </system.web>
  <!-- When deploying the service library project, the content of the config file must be added to the host's 
  app.config file. System.Configuration does not support config files for libraries. -->
  <system.serviceModel>
    <services>
      <service name="WcfServiceLibrary1.Service1">
        <host>
          <baseAddresses>
            <add baseAddress = "http://localhost:8733/Design_Time_Addresses/WcfServiceLibrary1/Service1/" />
          </baseAddresses>
        </host>
        <!-- Service Endpoints -->
        <!-- Unless fully qualified, address is relative to base address supplied above -->
        <endpoint address="" binding="basicHttpBinding" contract="WcfServiceLibrary1.IService1">
          <!--

              automatically.
          -->
          <identity>
            <dns value="localhost"/>

        </endpoint>

        <!-- This endpoint does not use a secure binding and should be secured or removed before deployment -->

      </service>
    </services>

      <serviceBehaviors>
        <behavior>
          <!-- To avoid disclosing metadata information, 
          set the values below to false before deployment -->
          <serviceMetadata httpGetEnabled="True" httpsGetEnabled="True"/>
          <!-- To receive exception details in faults for debugging purposes, 
          set the value below to true.  Set to false before deployment 
          to avoid disclosing exception information -->
          <serviceDebug includeExceptionDetailInFaults="False" />
        </behavior>

</configuration>

你能在浏览器中看到该服务可用吗？

【解决方案1】：

我认为你的问题正如你在问题中所说的那样“You are trying to consume the service in a class library and calling the class library from another project."请参阅此链接以获取原始答案。link

要解决您的问题，您只需将客户端绑定详细信息复制到主调用方项目配置文件即可。

  <system.serviceModel>
    <bindings>
      <basicHttpBinding>
        <binding name="BasicHttpBinding_IService1" />
      </basicHttpBinding>
    </bindings>
    <client>
      <endpoint address="http://localhost:8733/Design_Time_Addresses/WcfServiceLibrary1/Service1/"
        binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IService1"
        contract="ServiceReference1.IService1" name="BasicHttpBinding_IService1" />
    </client>
  </system.serviceModel>

让我看看这是否能解决问题。

【解决方案2】：

为您的服务名称和合同尝试使用完整命名空间的全名标识符。

<service name="SOLUTIONNAME.WcfServiceLibrary1.Service1">
     <endpoint address="" binding="basicHttpBinding" 
     contract="SOLUTIONNAME.WcfServiceLibrary1.IService1">
     ...

 </service>
