从CompactFramework客户端使用Web服务

Question

我正在尝试调用这样的webservice方法：

myService.Register("mystring");

webmethod定义只是：

[WebMethod]
public void Register(string s)
{
}

但是我收到以下System.InvalidOperationException：

“不期望使用System.String类型。使用XmlInclude或SoapInclude属性指定静态未知的类型。”

谷歌没有提出任何有用的东西，而且我处于死胡同，所以欢迎提出建议。到目前为止，我唯一的想法是它存在某种不匹配，因为CF使用不同版本的System.dll来处理Web服务项目。

这是因为我使用了Web引用的子类，并且还使用了一个接口，即：

public class MyWebServiceReference : RawWebServiceReference, IService {}

该接口位于RawWebServiceReference和MyWebServiceReference的单独项目中，其中一些方面导致错误。
