        class Program
        {
                static void Main(string[] args)
                {
                        Dictionary<string, string> dict = new
Dictionary<string, string>();
                        for (int ii = 0; ii < 20; ii++)
                        {
                                string num = ii.ToString();
                                dict.Add("k" + num, "v" + num);
                                Print(dict);
                        }

                        Console.WriteLine();
                       
Console.WriteLine("--------------------------------------------------------------------");
                        Console.WriteLine();
                        dict.Clear();

                        for (int ii = 19; ii >= 0; ii--)
                        {
                                string num = ii.ToString();
                                dict.Add("k" + num, "v" + num);
                                Print(dict);
                        }
                        Console.Read();
                }

                static void Print(Dictionary<string, string> dict)
                {
                        foreach (KeyValuePair<string, string> pair in dict)
                        {
                                Console.WriteLine(pair.Key + "," + pair.Value);
                        }
                        Console.WriteLine();
                        Console.WriteLine("---");
                        Console.WriteLine();
                }
        }
}

Expected: The key value pairs should remain in the order they were added.

Actual (MonoWindows): The order is correct after the 7th addition, but the 8th
pair is put at the beginning, followed by the 9th and 10th. When the 11th is
added the order completely changes in another way that is wrong.

Actual (MonoMac): Same behavior as MonoWindows for the first 10 pairs, but when
the 11th is added the order changes in a way that is different than both .NET
and MonoWindows.
