Kentico CMS 6, the most recent release from Kentico Software, now includes a healthy dose of API examples right inside the Kentico installation. What's even more exciting is that these examples are functionally interactive!
If you are like me, Classic ASP (Active Server Pages) still remains in the toolbox, standing by for that next 'simple' project. Or maybe there's a web app you would like to write in .Net, but you need to prototype business logic with a simple UI? In my opinion, Classic ASP fits the bill.
