Deserialize Json object from WCF RESTful Service

I have WCF RESTful Service declaration as below

[OperationContract]
[WebInvoke(Method = "GET", UriTemplate = "GetJson/{id}", ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped)]
EmployeeJSON GetEmployeeJSON(string id);

I get EmployeeJSON object from WCF RESTful Service as below

public EmployeeJSON GetEmployeeJSON(string id)
    {
        List<EmployeeJSON> employees = new List<EmployeeJSON>()
        {
             new EmployeeJSON() {Name="Sumanth",Id=101,Salary=5000.00 },
             new EmployeeJSON() {Name="Ehsan",Id=102,Salary=6000.00 },
        };

        var Employee = (from x in employees
                        where x.Id.ToString() == id
                        select x);


        return Employee.FirstOrDefault() as EmployeeJSON;
    }

I call the WCF RESTful service from client as below

var request = (HttpWebRequest)WebRequest.Create("http://localhost:1249/Service1.svc/GetJson/101");
        HttpWebResponse response = request.GetResponse() as HttpWebResponse;
        Stream stream = response.GetResponseStream();
        StreamReader reader = new StreamReader(stream);
        string json = reader.ReadToEnd();

And I get json value as follows

{"GetEmployeeJSONResult":{"Id":101,"Name":"Sumanth","Salary":5000}}

Now I am trying to Deserialize the above json as follows

JavaScriptSerializer serializer = new JavaScriptSerializer();
Employee responseObject = serializer.Deserialize<Employee>(json);

The Employee class structure is as follows at client side...

public class Employee
{
    public string Name { get; set; }
    public int Id { get; set; }
    public double Salary { get; set; }
}

But the result I am getting is Id as 0, Name as null and Salary as 0.0

How can I deserialize the JSON object?

Your Employee class didnt match the structure of the JSON string. This class is:

public class EmployeeContainer
{
        public Employee GetEmployeeJSONResult { get; set; }
}

...

Employee responseObject = JsonConvert.DeserializeObject<EmployeeContainer>(json)?.GetEmployeeJSONResult;
