我应该使用ClientBase <t>还是我的WCF客户端的通道工厂

Question

我已经在我的服务器上创建了一些WCF服务，现在我已经实现了客户端，我基本上只有两种方式：

使用ClientBase实现

function_score: {
  query: { match: {
    field => term,
  }},
  score_mode: :avg,
  script_score: {
    script: {
      inline: "4 * (1 + Math.log(2 + _score))",
    }
  },
}

使用ChannelFactory

public class SampleServiceClient : ClientBase<ISampleService>, ISampleService
{
    public SampleServiceClient(Binding binding, EndpointAddress remoteAddress) : 
            base(binding, remoteAddress)
    {
    }

    public string SampleMethod(string msg)
    {
        return base.Channel.SampleMethod(msg);
    }
}

一个优于另一个的优势是什么？ public ISampleService GetService(Binding binding, EndpointAddress remoteAddress){ ChannelFactory<ISampleService> channelFactory = new ChannelFactory<ISampleService>(binding, address); return channelFactory.CreateChannel(); } 中是否还有其他功能？有最好的做法吗？
