A couple of days ago i found a great framework called AForge.NET.
AForge.NET is a C# framework designed for developers and researchers in the fields of Computer Vision and Artificial Intelligence – image processing, neural networks, genetic algorithms, machine learning, robotics, etc.
This is a C# class which allows you to create Web and WinForm captcha control.
The class is very configurable, so finaly you could create a Captcha that suits your needs.
You can hold the Captcha secret key as a session or an encrypted cookie variable.
Well, this is not a new technique, but i couldn’t find any decent c# code that makes it work – so i’ve decided to write my own.
Once upon a time there were objects like ASPJeg which made it possible to manipulate images files – resize, convert and much more…
Lucky for us those times are gone and now we have a great framework called .NET, so why not use it ?
