Why use ThreadStart?

Question

Can somebody please clarify why we use ThreadStart?

new Thread (new ThreadStart (Update)).Start(); -Versus-
new Thread (Update).Start(); // Seems more straightforward

private void Update() { }

You don't have to. If you do, only you can say why...

Since C# 2, method groups (i.e. references to a method via its name) are implicitly convertible to delegates with the same signature. Since the Thread constructor takes a ThreadStart, you can pass it a method group with the same signature as ThreadStart.
