Kaliko CMS - Open source ASP.NET CMS

Kaliko CMS is a powerful and flexible content management system for ASP.NET that will help you to develop everything from a full blown website to a single campaign page where content is required to be editable. The framework approach also doesn't set any boundaries on how you structure your website or content. It's also very easy to extend the framework with content types if the ones included in the core doesn't quite match the requirements.
