    public static void NotImplementedMethod(float f)
    {
      throw new NotImplementedException();
    }
    public static void Main()
    {
      try
      {
        NotImplementedMethod(0);
      }
      catch(NotImplementedException e)
      {
        Console.WriteLine("Exception: {0}", e);
      }
