Missing method exception on webservices

Vote:
 

Hi, I'm prety new to EPi CMS. I have a legacy application to support which was designed to work on EPi 7. It has a webservice, codebehind is a C# class. The class has methods such as getChildPage, getVPP etc. I am aware of the shift of EPi's webservices to REST API and the fact that the webservices is officially gone after 8 onwards. Now my need is to work that out with a new instance of EPi 8.10. I added a webservice folder manually(root IIS), an asmx file inside and a dll. It works fine with 7.0, is there any tweaks that I can do to make it compatible to work with EPi8 and onwards? Please help, thanks in advance.

Reference:

[System.Web.Services.Protocols.SoapDocumentMethodAttribute("http://episerver.com/episerversample/webservices/GetChildPage", RequestNamespace="http://episerver.com/episerversample/webservices/", ResponseNamespace="http://episerver.com/episerversample/webservices/", Use=System.Web.Services.Description.SoapBindingUse.Literal, ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Wrapped)]
        public string[] GetChildPage(string PageId) {
            object[] results = this.Invoke("GetChildPage", new object[] {
                        PageId});
            return ((string[])(results[0]));
        }

class file:

 [WebMethod(Description = "Get child page list")]
        public List GetChildPage(string PageId)
        {
            List ChildPageList = new List();
            var PageList = EPiServer.DataFactory.Instance.GetChildren(new PageReference(PageId), LanguageSelector.AutoDetect(true));
            foreach (var page in PageList)
            {
                ChildPageList.Add(page.ContentLink.ID + "," + page.Name);
            }

            return ChildPageList;
        }
