The following program throws System.InvalidOperationException when compiled
under Mono but is fine when compiled with .Net

class Program
{
    static public IEnumerable<string> Empty
    {
        get
        {
            string[] strings = new string[] { };
            foreach (string s in strings)
            {
                yield return s;
            }
        }
    }

    static void Main()
    {
        IEnumerator<string> enumerator = Empty.GetEnumerator();
        enumerator.MoveNext();
        if (enumerator.Current == null)
        {
            Console.WriteLine("Successful");
        }
    }
}
