Reporting Services 2005 And XML DataSource (as WebService)

I'm trying to build WebService to use result as DataSource for RS 2005 (XML DataSource).

But I have a strange problem.

I have WebMethod with parameters.

When I'm testing my WS in browser then everything works just fine.


But... When I'm trying to call this web-service from VS2005 environment then something strange happens.

Looks like VS passing parameters incorrectly to my WS (not passing at all!)


I've created very simplyfied version just to check parameters:

using System.Xml;
using System.Xml.Serialization;
using System.Messaging;
using System.Text;
using System;
using System.Web.Services;
[WebService(Namespace = "http://company.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public class GetRemoteData : System.Web.Services.WebService
{
[WebMethod]
public XmlElement GetData(string CompanyName, string FunctionName, string ParameterList)
{
XmlDocument xmlDocument = new XmlDocument();
XmlElement xmlElement1;
xmlElement1 = xmlDocument.CreateElement("parameters", "values", "urn:errors");
xmlElement1.InnerText = String.Format("{0}, {1}, {2}", CompanyName, FunctionName, ParameterList);
return xmlElement1;
}
}



In the browser WS returns all passed parameters back correctly. VS - not.


What's wrong with my code? Why MSDN example works fine?
Do I need to specify some undocumented (soap specific) attributes?


Where I can find full tutorials how to create RS-compatible web-service?
