C# WCF流在调试时起作用，但在部署时不起作用

我有一个向WCF web服务提交大量数据的应用程序。由于数据可能很大，我想使用流式传输模式，这样我就可以在数据进入时处理数据，而不是缓冲所有数据

当Im调试应用程序时，流媒体按预期工作。一旦我真的将服务发布到我的IIS服务器上，流式传输就不再工作了，数据似乎只是得到了缓冲

我通过在web服务函数的开头放置一个

抛出新异常来测试它，并更改源流以提供“无限数据”

以下是服务器源代码：

[ServiceContract]
public class Service1
{
    [OperationContract]
    public void SubmitData(Stream stream)
    {
        throw new Exception("Test");
        using (var reader = new StreamReader(stream))
        {
            string line = reader.ReadLine();
            // Do Something...
        }
    }
}

Service1Client client = new Service1Client();
client.Endpoint.Address = new EndpointAddress(address);
client.Open();
using (var stream = new InfiniteDataStream())
    client.SubmitData(stream);
client.Close();

最后一条评论指出这是一个在.NET4.5中修复的bug，但我是用4.6.1构建的

另外，我的服务器运行的是IIS 8.5，所以我决定在我的本地Win10机器上尝试相同的测试，该机器有IIS 10，仍然在做同样的事情

使用Wireshark，我能够确认数据正在流式传输到服务器，而服务器无法处理数据。
我还尝试将
transferMode=“Streamed”
更改为
transferMode=“StreamedRequest”
，运气不好。
将
抛出新异常
行代码替换为写入日志文件，表明代码本身没有问题，在本地运行的IIS中托管的服务实例下，从客户端到服务器的请求流按预期工作。
重复？你读过“是”吗？有一次我偶然发现，被接受的答案引用了我在更新中引用的相同MSDN线程帖子。声明该问题在.Net 4.5中已修复，只是为了查看该问题是否与SSL/HTTPs有关。您是否尝试过改用非安全绑定？@EugeneKomisarenko是的，我尝试从basicHttpBinding更改为basicHttpBinding，并从绑定中删除了标记，同样的结果在进行进一步更改之前，我真的建议启用WCF诊断，然后看看您是否可以首先从这些日志中检测到问题。如果我错了，请纠正我，但这不会只影响响应吗？我正在尝试对请求进行流式处理。您是对的，先前版本的答案是关于响应的流式处理的，请参阅更新的答案，了解抛出异常的副作用。感谢您的发现，我的原始测试代码中一定存在另一个问题，那就是将流写入文件，直到流被完全发送，它才写入文件。所以我想我引入了一个关于异常测试的新问题。但无论最初的问题是什么，我都不确定，因为现在它工作正常了。
