浏览器上的WCF服务404错误

Question

这可能是非常常见的问题并且多次询问，但我在过去2天内对此问题进行了排查。

我在下面创建了WCF服务：

IStudentService.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;
using System.ServiceModel.Web;

namespace WcfStudentService
{
    // Defines IStudentService here
    [ServiceContract ]
    public interface IStudentService
    {       
        [OperationContract]
        [WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Json)]
        string GetData();

    }
}

StudentService.svc.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;
using Newtonsoft.Json;

namespace WcfStudentService
{
    // StudentService is the concrete implmentation of IStudentService.
    public class StudentService : IStudentService
    {
public string GetData()
        {
            return  "{ Result : " + "Success" + " }";
        }

    }
}

的Web.config（更新）：

当我从WcfTestClient调用它时，上面的服务返回结果但是当我在浏览器上浏览我的服务URL时（ 192.168.X.XXX:8282/IStudentService.svc/GetData ）它会抛出404错误。

我谷歌并发现以下两个线程有​​用：

Thread1 Thread2

但它仍然不起作用。请帮忙。

任何帮助
