A point I have found after using events in .Net for many years is the repetitive need to check the event for a null handler on every invocation. I'm yet to see a piece of live code that does anything but not call the event if it is null.

What I have started doing is to put a dummy handler on every event I create to save the need to do the null check.

public class Metronome
{
    public event EventHandler Tick =+ (s,e) => {};

    protected virtual void OnTick(EventArgs e)
    {
        Tick(this, e);  // now it's safe to call without the null check.
    }
}
