如何使用wsHttpBinding

我之前的WCF服务是使用的BasicHttpBinding，服务的web.config只要这样配置  <system.serviceModel>
    <bindings>
      <basicHttpBinding>
        <binding maxBufferPoolSize="5242880000" maxBufferSize="655360000" maxReceivedMessageSize="655360000">
          <security mode="None"/>
          <readerQuotas maxArrayLength="655360000" maxStringContentLength="655360000" maxBytesPerRead="655360000" />
        </binding>
      </basicHttpBinding>
    </bindings>
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <!-- 为避免泄漏元数据信息，请在部署前将以下值设置为 false 并删除上面的元数据终结点 -->
          <serviceMetadata httpGetEnabled="true"/>
          <!-- 要接收故障异常详细信息以进行调试，请将以下值设置为 true。在部署前设置为 false 以避免泄漏异常信息 -->
          <serviceDebug includeExceptionDetailInFaults="false"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
  </system.serviceModel>后台通道工厂直接创建通道this._Binding.MaxReceivedMessageSize = int.MaxValue;
            this._Binding.MaxBufferPoolSize = int.MaxValue;
            this._Binding.MaxBufferSize = int.MaxValue;
            this._Binding.SendTimeout = new TimeSpan(1, 1, 1);
            this._ReaderQuotas.MaxArrayLength = int.MaxValue;
            this._ReaderQuotas.MaxStringContentLength = int.MaxValue;
            this._ReaderQuotas.MaxBytesPerRead = int.MaxValue;
            this._Binding.ReaderQuotas = this._ReaderQuotas;
            EndpointAddress address = new EndpointAddress(ConfigurationManager.AppSettings[key]);
            this._Factory = new ChannelFactory<T>(this._Binding, address);
            this._Channel = this._Factory.CreateChannel();
客户端我只需要在app.config指定服务  <appSettings>
    <add key="svc" value="http://localhost:5802/Service.svc"/>
  </appSettings>
客户端代码就可以直接调用服务的方法
DataTable dt = factory.Channel.GetData("select * from t_parameters", null, true, "BaseConnString");但是因为BasicHttpBinding不支持事务，现在想要换成wsHttpBinding，我的配置需要如何修改
