Best Practices to Declare Events

Hello,
I was reading in the book: Chapter 6, Page: 147 lists the following code:

Code:

public class MyActivity : Activity
{
    public static readonly DependencyProperty SomethingHappenedEvent;
    
    public event EventHandler SomethingHappened
    {
        add
        {
            base.AddHandler(MyActivity.SomethingHappenedEvent, value);
        }
        
        remove
        {
            base.RemoveHandler(MyActivity.SomethingHappendEvent, value);
        }
    }
}

Now, my question: is it a good practice to declare the event with the "readonly" modifier? I did not use to do so my self. Also, I'm using VS'08 with WF 3.5; if I declare a DependencyProperty or a DependencyEvent I use code snippets 'wdp' and 'wde' respectively and the code generated does not include the readonly modifier.

Thank you.
