The JavaScriptSerializer is defined in the System.Web.Script.Serialization namespace and note the usage of System.Web namespace… It is highly recommended that you use JSON.NET instead this demo is just to demonstrate that this one is also possible.

using System.Web.Script.Serialization;
namespace ConsoleApp1
    public class Employee
        public string FirstName { get; set; }
        public string LastName { get; set; }
        public DateTime JoinedDate { get; set; }

        static void Main(string[] args)
            Employee emp = new Employee();

            emp.LastName = "Balu";
