How would this be used in another project?

How would I use the wrapper in my existing project? With ReCaptcha.Net all I need to do is install a nuget package. It's a portable solution.

This one is complicated. The "wrapper" does not seem to be separated from the webapp. For example, there's the MVC object on the Basic page that refers to Generated Code not mentioned in your explanation on Dev Kimchi and not coming from the Recaptcha.Wrapper package...

There is no ReCaptcha.Wrapper package, but ReCaptcha.NET and ReCaptcha.NET.MVC packages. If you want to use ReCaptcha.NET on your ASP.NET MVC application, you should reference both ReCaptcha.NET and ReCaptcha.NET.MVC packages.

WebApp in this repo is just an example how to use this extension library, which is independent from the packages. If you're mentioning MVC.Home.ActionNames.Basic..., this comes from a different package called, T4MVC.

The code line I stated above, this is what you actually need to do to render the ReCaptcha control. I don't see any more explanation necessary.
