WCF消息合同版本控制

我创建了一个WCF服务，并使用消息合同将数据传递给客户端。 我在消息合同中添加了一个新成员，但我没有更新客户端的服务引用。 现在根据WCF版本控制旧客户端应该可以工作，但在我的情况下，当我获得服务调用后的数据时，一些成员被填充，一些成员为空（新旧邮件合同之间通用的成员。） 我也使用transport ='Streamed'进行服务绑定。 我想知道我是否遗漏了什么。 我遇到了与数据合同相同的问题。 提前谢谢。

Hi, I had created a WCF service and used message contract to pass data to client. I added a new member in message contract and I did not update the service reference of the client. Now as per WCF versioning the old client should work,but In my case when I get the data after service call,some of the members are populated and some are null(members that are common between the old and new message contract). I am also using transport='Streamed' for the service binding. I would like to know whether I am missing something. I faced the same issue with data contracts. Thanks in advance.
