Encrypting FormsAuthenticationTicket throws Null reference exception at System.Web.Util.UrlUtils.Combine(String basePath, String relPath)

//Compile ready program used .Net 4.5 as a base
using System;
using System.Web.Security;
class Program
    {
        static void Main(string[] args)
        {
            try
            {
                FormsAuthenticationTicket formsTicket = new FormsAuthenticationTicket(
                    2,
                    "User",
                    DateTime.Now,
                    DateTime.Now.AddHours(10d),
                    true,
                    "DeviceID"
                    );
                var token = FormsAuthentication.Encrypt(formsTicket);
                Console.WriteLine(token);
            }
            catch (Exception e)
            {
                Console.WriteLine(e.Message + e.StackTrace);
            }
            Console.ReadKey();
        }

    }
