Kudos to Ben and the rest of the Captcha team.
Today I downloaded the binaries for reCaptcha.NET for a web page that I was setting up and it worked out of the box. No recompiles necessary:
- Drop the Recaptcha.dll in the bin directory of the ASP.NET app.
- Get your public/private key.
- Insert this in your page:
<recaptcha:RecaptchaControl ID="recaptcha" runat="server" Theme="red" PublicKey="YourKey" PrivateKey="YourOtherKey"/>
- Hit refresh. Ta da!
