Kevin Gearing of DotNetFreak has released an updated CAPTCHA control for .NET. Not only compiled against the latest version, there are a lot of new features, too:
Version 2 of FormShield builds on the previous .NET 1.1 version, adding a wealth of new features, options and accessibility improvements. The most notable feature addition is the capability for FormShield to now automatically generate a spoken version of the value shown on the image to aid with accessibility legal compliance. This however is just one of a handful of major new features, not to mention the number of improvements and changes made since the previous version.
If you’re looking for an ASP.NET CAPTCHA control, this one is worth checking out.
