You maybe know, I've made a fork of the project and have implemented support of the latest version of the reCAPTCHA API (including the new widget support) with keeping of full backward compatibility with the Recaptcha for .NET assemblies. Source code is also mirrored on GitHub at https://github.com/evnik/reCAPTCHA4net.
I believe my changes could be ported back to the Recaptcha for .NET project. Let me know if you interested in, and I will create a pull request.
