The License Agreement
The license agreement for the ASP.NET Starter Kits specifies that apart from some restrictions, you’re allowed to use them for any commercial or non-commercial purposes. Thus, you’re allowed to create your own websites based on the CSK code and use them for your own needs.
The complete license agreement terms for using the starter kit application can be found at http://www.asp.net/samplessourcelicense. Even though the terms are pretty relaxed, please read them carefully before starting to create your websites based on the CSK.
