ASP.NET WebService ignoring return: XmlArray ElementName

Question

This is as weird as it gets. Name given in XmlArray attrib's ElementName appears in WISDL but not in actual response. Running under 3.5 (2.0.50727 for IIS AppPool).

After more detailed digging -- autogenned WSDL has different declarations for POST/GET vs SOAP responses and the diff is that they just reference the autogenned elem/type for array and not the whole response type/elem which has new name.

The question still remians - WHY is this happening and more importantly how to fix it?

Here are the Details:

WebMethod:

    [WebMethod]
    [return: XmlArray(ElementName = "TickTick")]
    public TTickerItem[] GetActiveTickerItems2(uint version, uint language, uint locale, int startIndex, int maxItems)

In WSDL:

<s:element name="GetActiveTickerItems2Response">
  <s:complexType>
    <s:sequence>
      <s:element minOccurs="0" maxOccurs="1" name="TickTick" type="tns:ArrayOfTTickerItem" /> 
    </s:sequence>
  </s:complexType>
</s:element>

<wsdl:message name="GetActiveTickerItems2SoapIn">
  <wsdl:part name="parameters" element="tns:GetActiveTickerItems2" /> 
</wsdl:message>
<wsdl:message name="GetActiveTickerItems2SoapOut">
  <wsdl:part name="parameters" element="tns:GetActiveTickerItems2Response" /> 
</wsdl:message>

Auto-genned test page shows examples with new name (TickTick).

Actual Response:

<ArrayOfTTickerItem xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://tempuri.org/"&gt;
<TTickerItem>
  <m_message>New Ticker 1st Message</m_message> 
  <m_priority>2</m_priority> 
  <m_messageType>0</m_messageType> 
  <m_data1>0</m_data1> 
  <m_data2>13</m_data2> 
</TTickerItem>
. . . . . . . .
</ArrayOfTTickerItem>

Slightly different declarations for GET/POST - misses the new name:

<wsdl:message name="GetActiveTickerItems2HttpGetOut">
  <wsdl:part name="Body" element="tns:ArrayOfTTickerItem" /> 
</wsdl:message>
. . . . . . . 
<wsdl:message name="GetActiveTickerItems2HttpPostOut">
  <wsdl:part name="Body" element="tns:ArrayOfTTickerItem" /> 
</wsdl:message>

It can still be the matter of some settings, part of web.config (I have just plain add name="HttpGet" and HttpPost under //system.web/webServices/protocols xpath which has always been enough) ...

Answer 1

Have you tried updating the web reference in your asp.net project?

Answer 2

I'm afraid I'll have to close this one as a bug in ASP.NET since I have consistent repro and no one said that it worked with their setups. Will keep it on for a few more days, just in case.
