What open-source QR Code Generator would you recommend?

Question

I'm looking for a library to generate QR codes in .NET I've stumbled across a few paid ones, but very few free ones that look any good. Anyone have experience with a good free open-source library?

Thanks

He's not asking what the best one is, he's just asking for recommendations. I think it's valid. — Jack Marchetti, Apr 12 '11 at 19:49
@Jack Marchetti - it falls under "your answer is provided along with the question, and you expect more answers: "I use ______ for ______, what do you use?" from the faq — Daniel A. White, Apr 12 '11 at 19:52
@Daniel - I'm not using any framework at the moment. I'm trying to find one to use. — Micah, Apr 12 '11 at 21:02

In past I used this one.
It's really "heavy" (about 6MB) but it worked for me and it's released under Code Project Open License (CPOL). I forgot: C# source code is provided.
Another one is MessagingToolKit, which is provided even with a free license; I don't remember (excuse me) if QR is inside free license or not.

What open-source QR Code Generator would you recommend?
