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, an API example is worth a 1000 lines of code! What's more satisfying than having a well documented API with examples when it is two o'clock in the morning and deadlines are quickly approaching? How about API examples that are live and actually work right within your project!
