Beginner problem with ASP.NET Web Service and IIS

I am newbie in .NET. Now I am trying make my first ASP.NET Web Service.

I create ASP.NET Web Service Project and use default Web Methods generated by Visual Studio 2010.

I tested this service in Visual Studio, it works good.

Then I added virtual directory on IIS, directory name is test. I use Windows Server 2003 Standard.

And tried access to web service via localhost.

http://localhost/test/Service1.asmx

I got this error message:

The XML page cannot be displayed 
Cannot view XML input using XSL style sheet. Please correct the error and then click the Refresh button, or try again later.

I checked this files:

Service1.asmx.cs

using System.Coll开发者_如何学运维ections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;

namespace WebService1
{
    /// <summary>
    /// Summary description for Service1
    /// </summary>
    [WebService(Namespace = "http://tempuri.org/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]
    // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. 
    // [System.Web.Script.Services.ScriptService]
    public class Service1 : System.Web.Services.WebService
    {

        [WebMethod]
        public string HelloWorld()
        {
            return "Hello World";
        }
    }
}

What can be bad? Thank for support.

Looks like ASP.NET is not enabled on the IIS machine.

You might want to check your windows components control panel -> Programs and Features -> Turn Windows features on or off and check if the Internet Information Services/World Wide Web Services/Application Development Features/ASP.NET feature is enabled on the machine running IIS and check to install it if it's not enabled.

.Try running aspnet regiis utility command found in C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727 folder.Maybe script maps not updated correctly.If you already have IIS installed,Did you installed IIS after installing .NET framework?

aspnet_regiis -i
