Здравейте колеги,

Имам изключително досаден проблем и не знам къде да търся решението. Естествено потърсих във форума, но за жалост без резултат. Когато се опитам да кача задача в джъдж ми изписва Compile time error

Кодът е следния :

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace Excellent_Result
{
    class Program
    {
        static void Main(string[] args)
        {
            var grade = double.Parse(Console.ReadLine());
            if (grade >= 5.50)
            {
                Console.WriteLine("Excellent!");
            }
        }
    }
}

Супер базов и работи без проблем във VS 

Грешката, която получавам съдържа следната информация:

Ако някой има идея защо не го приема бих бил благодарен да сподели :)
