c# - Service Reference 为 ServiceStack 生成不正确的代理

Question

我有一个服务堆栈服务，在同一个命名空间中包含以下请求和响应类

public class GetContactMasterData
{

}

public class GetContactMasterDataResponse
{
    public IdDescription[] EntityTypes { get; set; }
    public IdDescription[] NameTypes { get; set; }
    public IdDescription[] AddressTypes { get; set; }
    public ResponseStatus MyResponseStatus { get; set; }
}

我使用 soapUI 成功测试了该服务。这是回应

<s:Envelope xmlns:s="http://www.w3.org/2003/05/soap-envelope">    
   <s:Body>
      <GetContactMasterDataResponse xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.servicestack.net/types">
         <AddressTypes>
            <IdDescription>
               <Description>Home</Description>
               <Id>1</Id>
            </IdDescription>
            ...
         </AddressTypes>
        <EntityTypes>
           <IdDescription>
              <Description>Corporation</Description>
              <Id>1</Id>
           </IdDescription>
           ... 
        </EntityTypes>
        <MyResponseStatus i:nil="true" />
        <NameTypes>
           <IdDescription>
              <Id>4</Id>
              <Description>Other</Description>
           </IdDescription>
           ...
        </NameTypes>
      </GetContactMasterDataResponse>
   </s:Body>
</s:Envelope>

当我创建一个控制台应用程序来测试此服务时，服务引用会生成一个代理对象。 intellisense 是这样引导你调用 GetContactMasterData 方法的

GetContactMasterData(出 IdDescription[]，出 ResponseStatus myResponseStatus，出 IdDescription[] NameTypes):IdDescription[] addressTypes

我的问题是:为什么 EntityTypes 和 NameTypes 成为输出参数，而 addressTypes 成为方法的返回类型？

包含在 ServiceStack 的 SOAP Support wiki 中使用 SOAP 时需要注意的限制:

Since VS.NET's Add Service Reference is optimized for consuming .asmx or WCF RPC method calls it doesn't properly support multiple return values (e.g. when you also want a ResponseStatus property) where it will generate an ugly proxy API complete with out parameters.

If you want to ensure a pretty proxy is generated you should only have 1 first-level property which contains all the data you want to return.
