What's the most elegant lambda expression (action) that does nothing?

Question

So I currently have the following code:

    BCLThread bclThread = new BCLThread(() => Thread.Sleep(0));

because I can't think of another way to state that I actually don't want that method to do a thing. Is there any other more elegant way of achieving this?

Thanks

Answer 1

Why not

BCLThread bclThread = new BCLThread(() => {});

?

Answer 2

Action a = delegate { };
Action b = () => { };
