This is a great tutorial on using reCaptcha in MVC and works with the currently newest release.

This was a good tutorial. I used this as the basis of creating my own HTML Helper. The only thing I don't like about my solution is that I assign the captcha is valid value to the ViewBag in the ActionFilter and then examine it in the Controller Action. I would like it to be enough to decorate the action with the ActionFilter attribute. – Umar Farooq Khawaja Sep 20 '11 at 18:31

Stack Overflow, which is written using ASP.NET MVC, uses reCAPTCHA. You can find out more about reCAPTCHA at Digitizing Books One Word at a Time and even watch Jeff Atwood talk about reCAPTCHA within Stack Overflow during his talk at PDC 2008.

Check out RecaptchaMvc. It's a framework that uses the reCAPTCHA service and ASP.NET MVC.
