[Mono-list] Error compiling webservice: An element with the same key already exists in the dictionary.

[Andrus]

I tried to run web service sample from silverlight.net samples

http://localhost/WebServicesApp_Web/SimpleAsmx.asmx

but got error below.
From Visual Web Developer Express 2008 this service runs OK.

How to fix ?

Additional question:
How to return IList<Customer>  type from web service method call in MONO ?


Andrus.

-------- SimpleAsmx.asmx contains:

ļ»æ<%@ WebService Language="C#" CodeBehind="~/App_Code/SimpleAsmx.cs"
Class="SimpleAsmx" %>

------ App_Code/SimpleAsmx.cs contains:

ļ»æusing System;
using System.Collections;
using System.Web;
using System.Web.Services;
using System.Web.Services.Protocols;

[WebService(Namespace = "http://tempuri.org/";)]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public class SimpleAsmx : System.Web.Services.WebService
{

    public SimpleAsmx()
    {
    }

    [WebMethod]
    public string HelloWorld()
    {
        return "Hello World";
    }

    [WebMethod]
    public string SayHelloToMe(string name)
    {
        return string.Format("Hello {0}, how are you?", name);
    }

}


------- Output:

Server Error in '/' Application
