Custom Web Service in vti_bin folder does not show Service description

Question

I've used the Walkthrough: Creating a Custom ASP.NET Web Service from MSDN to create my cusom WCF Service and deploy to my Sharepoint 2010 server.

http://myserver/_vti_bin/randomchatwebservice.asmx seems to work fine and it shows service methods. But I get "The webpage cannot be found" when I try to reach http://myserver/_vti_bin/randomchatwebservice.asmx?wsdl or http://myserver/_vti_bin/randomchatwebservice.asmx?disco.

I have RandomChatWebServicedisco.aspx and RandomChatWebServicewsdl in C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\ISAPI and spdisco.aspx file has

<contractRef
  ref=<% SPHttpUtility.AddQuote(SPHttpUtility.HtmlEncode(
         spWeb.Url + "/_vti_bin/RandomChatWebService.asmx?wsdl"),
         Response.Output); %>
  docRef=<% SPHttpUtility.AddQuote(SPHttpUtility.HtmlEncode(
            spWeb.Url + "/_vti_bin/RandomChatWebService.asmx"),
            Response.Output); %>
  xmlns="http://schemas.xmlsoap.org/disco/scl/" />
<discoveryRef
   ref=<% SPHttpUtility.AddQuote(SPHttpUtility.HtmlEncode(
          spWeb.Url + "/_vti_bin/RandomChatWebService.asmx?disco"),
          Response.Output); %>
  xmlns="http://schemas.xmlsoap.org/disco/" />

definitions. What seems to be wrong?

Answer 1

@Melih Öztürk posted a solution to his own question:

contactRef part of the WSDL file seems to be not well-formed. I changed it and problem solved.

Answer 2

My recommendation is to deploy the custom web service to the Layouts (_layouts) folder rather than the ISAPI (_vti_bin) folder. All the issues with the disco and wsdl generation go away.
