sorry im so tired maybe that's way i cant see it:P

Did you delete your Main() method?

I have reformatted the code and removed two lines.
I did not add any functionality or correct anything other than making a Main() and making the methods static and removing the Console.ReadLine() calls that are causing you to need to press enter:

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

namespace ConsoleApplication1
{
   class WasteSchedul
   {
      public static void WriteMenuText()
      {
         Console.WriteLine("\n1 Bin 1");
         Console.WriteLine("2 Bin 2 ");
         Console.WriteLine("0 Exit the program");
         Console.Write("\nYour choice ");
      }

      private static void Bin1()
      {
         int count = 52;
         int p = 0;
         const int cols = 3;
         string montera = "";

         for (int i = 1; i <= count; i += 2)
         {
            montera += string.Format("{0,10} {1,2}", "Week", i);
            p++;
            if ((p >= cols) && (p % cols == 0))
            {
               Console.WriteLine(montera);
               montera = "";
            }
         }
         Console.WriteLine(montera);
         Console.WriteLine("\nBin number 1 is emptied the following weeks ");
         Console.WriteLine("-------------------------------------------------------");
      }

      private static void Bin2()
      {
         int count = 52;
         int p = 0;
         const int cols = 3;
         string montera = "";

         for (int i = 5; i <= count; i += 6)
         {
            montera += string.Format("{0,10} {1,2}", "Week", i);
            p++;
            if ((p >= cols) && (p % cols == 0))
            {
               Console.WriteLine(montera);
               montera = "";

            }
         }
         Console.WriteLine(montera);
         Console.WriteLine("\nBin number 2 is emptied the following weeks ");
         Console.WriteLine("-------------------------------------------------------");
      }

      public static void Main(string[] args)
      {
         int choice = -1;

         while (choice != 0)
         {
            WriteMenuText();
            choice = int.Parse(Console.ReadLine());
            switch (choice)
            {
               case 1:
               {
                  Bin1();
                  break;
               }
               case 2:
               {
                  Bin2();
                  break;
               }
            }
         }
      }
   }
}
