I have problems hosting a super simple asp xml service sending a correct soap request, but keep getting System.Web.Services.Protocols.SoapException: Server did not recognize the value of HTTP Header SOAPAction: http://www.quizmap.net/Add the service is as follows: <%@ WebService Language=C# class=MyClass %> using System.Web.Services ; public class MyClass { [WebMethod()] public int Add ( int a, int b) { return a + b ; } } Ive put the .asmx on root as well as under subfolders. Im new to this , so guess there is something basic im missing out on. Could it be that this type of service is not supported by my account at discountasp.net ?
