Cordial saludo


Quisiera saber si pueden hacer por favor un instructivo igualito a este, pero para Microsoft Visual Studio 2010 (la versión gratuita) o si lo tienen ya hecho ¡Perfecto!, saber la URL. Lo que pasa es que me presenta unos errores al momento de hacer el "Add Web Service Reference..." con :

The document at the url http://localhost/WorkShopUDP_v1/mensaje1.asmx was not recognized as a known document type.
The error message from each known type may help you fix the problem:
- Report from 'XML Schema' is 'Name cannot begin with the '%' character, hexadecimal value 0x25. Line 1, position 2.'.
- Report from 'DISCO Document' is 'Name cannot begin with the '%' character, hexadecimal value 0x25. Line 1, position 2.'.
- Report from 'WSDL Document' is 'There is an error in XML document (1, 2).'.
- Name cannot begin with the '%' character, hexadecimal value 0x25. Line 1, position 2.
Metadata contains a reference that cannot be resolved: 'http://localhost/WorkShopUDP_v1/mensaje1.asmx'.
The content type text/plain of the response message does not match the content type of the binding (application/soap+xml; charset=utf-8). If using a custom encoder, be sure that the IsContentTypeSupported method is implemented properly. The first 96 bytes of the response were: '?<%@ WebService Language="VB" CodeBehind="mensaje1.asmx.vb" Class="WorkShopUDP_v1.Service1" %>'.
If the service is defined in the current solution, try building the solution and adding the service reference again.

A todos ustedes sinceras gracias por hacer estos instructivos que sirven mucho a nosotros los desarrolladores.
