    {
        public static int X = 30;
        public static void Main()
        {
            var cX = new testme();
            cX.intX = 12;
            Console.WriteLine(cX.intX);
            cX.intX = X;
            Console.WriteLine(cX.intX);
            Console.ReadKey();
        }
    }
    class testme
    {
        public int intX
        {
            get;
            set;
        }
    }
}

Because you were using the field in a static context, in this case the method publicstaticvoid Main. Since your Program class just runs statically there is no instance and therefore you can’t access any instance members.
