端点为空？

Question

我收到以下错误：

ChannelFactory.Endpoint 上的 Address 属性为 null。 ChannelFactory 的 Endpoint 必须指定有效的地址

但是我有客户端端点的地址，这里发生了什么？

代码：

 ChannelFactory<CommService.ITwService> myChannelFactory 
 = new ChannelFactory<CommService.ITwService>();
 CommService.ITwService wcfClient1 = myChannelFactory.CreateChannel();

客户端：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>

  <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>
    <client>
      <endpoint address="http://localhost:8732/Design_Time_Addresses/CommService/Service1/"
        binding="wsHttpBinding" contract="CommService.ITwService"
        name="Super">
        <identity>
          <dns value="localhost" />
        </identity>
      </endpoint>
    </client>
    <services />
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <!-- To avoid disclosing metadata information, 
          set the value below to false and remove the metadata endpoint above before deployment -->
          <serviceMetadata httpGetEnabled="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" />

通过创建一个新项目解决了这个问题..创建文件并使用复制粘贴将代码复制到新项目..很奇怪。
