The library out there
Again, when having any task to do we should understand what it requires from both requirements view and also technical view. Later, do some search to see if it has been done by any active guy in the globe, even we can implement it ourself or here.
With reCaptcha also, I found some useful libraries there recaptcha-net, reCAPTCH.MVC and so forth.
How to use RecaptchaNet
I choose this because it does not require any dependency (as version 1.3).
