WCF SOAP响应命名空间问题

WCF返回空对象，尽管我可以从fiddler跟踪中看到数据正在返回。我确信这是名称空间的问题，但在阅读了所有文档之后，我看不出有什么问题！请求和响应SOAP如下：

请求：

POST https://x.x.x.x:9001/soap/ HTTP/1.1
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; MS Web Services Client Protocol 4.0.30319.34209)

Content-Type: text/xml; charset=utf-8
SOAPAction: "get_wsdl_version"
Host: x.x.x.x:9001
Content-Length: 236
Expect: 100-continue
Connection: Keep-Alive

        <soap:Body />
    </soap:Envelope>

编辑：添加WDSL代码段-从VS中提取

获取\u wsdl\u version（）-int
返回SOAP服务器的WSDL版本。这是用来检查的
客户端/服务器兼容性。
参数：无
例外情况：无

值得一提的是，我无法控制服务器端。我只需要使用我的代码中的服务，但我可以

提前谢谢

您能发布服务定义代码和客户呼叫代码plsTom吗？谢谢您关注我的问题。我刚刚添加了您要求的位。

Dim TestClient = New ServiceReference1.TableLampServiceClient

Dim Creds = New ServiceReference1.AuthInfo()
Creds.username = "xxx"
Creds.password = "yyy"

Dim TestVersion = TestClient.get_wsdl_version()
