Is it possible to create .wsdl from given assembly dll in commandline?

I have written MathService.cs file and then compiled it to SoapTest.dll
file. Then I used soapsuds to generate a wsdl from the given dll file. I did
get something, but it does not have any methods in it and namespaces look
very interesting.

Anyone succeded generating such file in commandline only?

***create schema command***
c:\>TestSoap\soapsuds -ia:SoapTest -os:MathService.wsdl

***MathService.cs sourcecode***
using System;
using System.Web.Services;

[WebService(Description="My First WS Test",
           Namespace="http://www.mytest.com/")]

public class MathService : WebService {

   [WebMethod(Description="sum given integers")]
   public int sum(int a, int b) {
    return (a + b);
   }

}

*** generated MathService.wsdl ***
