C# 未调用单向服务方法

我有一个WCF服务，它在单独的服务上调用单向操作。 我遇到的问题是没有收到单向服务呼叫（没有记录任何消息）。如果我更改

IsOneWay=false

，那么它将按预期工作

该服务托管在IIS中

代码已经精简到（我认为是）重要的部分

单程服务：

[ServiceContract]
public interface IOneWayService
{
    [OperationContract(IsOneWay = true)] // changing IsOneWay to false makes everything work as expected.
    void OneWayOperation(int param);
}



[ServiceBehavior()]
public class OneWayService : IOneWayService
{
    public void OneWayOperation(int param)
    {
        Log("OneWayService called.");
    }
}

发起呼叫的服务：

[ServiceContract]
public interface ITestService
{
    [OperationContract()]
    OperationResult DoThings();
}

[ServiceBehavior()]
public class TestService : ITestService
{
    public OperationResult DoThings()
    {
        ...
        ...

        if (some condition)
        {
            CallOneWayService();
        }

        return result;

    }

    private void CallOneWayService()
    {
        var cf = new ChannelFactory<IOneWayService>("IOneWayService");
        var channel = cf.CreateChannel();
        channel.OneWayOperation(5);
        cf.Close();
    }

}

[服务合同]
公共接口ITestService
{
[运营合同（）]
操作结果DoThings（）；
}
[ServiceBehavior（）]
公共类TestService:ITestService
{
公共操作结果DoThings（）
{
...
...
如果（某些条件）
{
CallOneWayService（）；
}
返回结果；
}
私有void CallOneWayService（）
{
var cf=新渠道工厂（“IOneWayService”）；
var channel=cf.CreateChannel（）；
通道.单向操作（5）；
cf.Close（）；
}
}

以及web.config：
