Using display data annotations in property grid c#

Question

I am creating a Windows Form Application in C# and using property grid in it. I am displaying properties of a Person class object in it and wanted to use Display data annotation to set property's description, display order of properties and other things. To implement the same I have added reference to System.ComponentModel.DataAnnotations in my code and code for my Person class is like this:

class Person
    {
        [Display(Name = "First Name", Order = 1,
        Prompt = "Enter First Name", Description = "Person First Name")]
        public string firstname { get; set; }
        [Display(Name = "Last Name", Order = 2,
        Prompt = "Enter Last Name", Description = "Person Last Name")]
        public string lastname { get; set; }
        [Display(Name = "Age", Order = 3,
        Prompt = "Enter Age", Description = "Person Age")]
        public int age { get; set; }
    }

But data annotations not working. Here is screenshot of property grid in my app.. screenshot of property grid

I am not able to understand why data annotation are not working in my code. Can anyone help out? Is there anything I am missing out? Do I need to implement any code segment to make them work?

Set the property PropertySort of your propertyGrid to PropertySort.NoSort and properties will be displayed in the order they are declared

propertyGrid1.PropertySort = PropertySort.NoSort;
