reCAPTCHA for .NET allows a developer to easily integrate Google's reCAPTCHA service (the most popular captcha control used by millions of sites) in an ASP.NET Web Forms or ASP.NET MVC web application.

The primary features of the library are:
* Renders recaptcha control with appropriate options.
* Verifies user's answer to reCAPTCHA's challenge.
* Supports ASP.NET 4.0, 4.5, and 4.5.1.
* Supports ASP.NET MVC 4 and 5.
* The library currently supports Google's reCAPTCHA API v1. Support for API v2 is coming soon and the support for v1 will remain in tact as long as Google does the same.

reCAPTCHA for .NET has the best and most up-to-date documentation among all the other competing libraries.
