//To compile the program, open a Visual Studio .NET command prompt (or any other command prompt session with the C# compiler in the path) and run this command:
//csc /t:exe /r:System.Web.dll WsHostTest.cs
//Put the exe file in a directory with an ASMX file. Heres the simple file Ive used in my tests:
//<%@ WebService Language="C#" Debug="true" Class="foo" %>
//using System.Web.Services;
//
//
//public class foo
//{
//    [WebMethod()]
//    public string echo(string input)
//    {
//        return input;
//    }
//}
//
//I also created a file with the SOAP message I wanted to use as input for the program. Here is the contents of this file:
//
//<?xml version="1.0" encoding="utf-8"?>
//<?xml version="1.0" encoding="utf-8"?>
//<soap:Envelope
//xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
//xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
//xmlns:xsd="http://www.w3.org/2001/XMLSchema">
//<soap:Body>
//<echo xmlns="http://tempuri.org/">
//<input>Howdy</input>
//</echo>
//</soap:Body>
//</soap:Envelope>
//</pre>
//
//To call the program, I entered this command line:
//
//WsHostTest echo.asmx http://tempuri.org/echo <soaptext.txt
