Method overloading in webservices created with Visual Studio 2005

When creating a webservice in Visual Studio 2005, the IDE adds the following WebServiceBinding:

[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]

This line indicates that your webservice conforms to the Web Services Interopability Organization's (WS-I) Baisc Profile 1.1. The Basic Profile defines a set of rules to which your webservice must conform.

One of its rules is that the webservice may not include method overloading. If you run a webservice that uses method overloading lile the one below, you will receive an errormessage telling that your service is not conform to WS-I Basic Profile v1.1:

Code:
using System.Web.Services;

[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public class Service : System.Web.Services.WebService
{
   [WebMethod(MessageName = "HelloWorld")]
   public string HelloWorld()
   { 
      return "Hello World";
   }
 
   [WebMethod(MessageName = "HelloWorldWithName")]
   public string HelloWorld(string name)
   { 
      return "Hello world " + name;
   }
}

Exception:

Message: Service 'Service' does not conform to WS-I Basic Profile V1.1. Please examine each of the normative statement violations below ...

To be able to still use method overloading, you need to change the WebServiceBinding as follows:
[WebServiceBinding(ConformsTo = WsiProfiles.None)]
