The Visual Studio LightSwitch Training Kit contains demos and labs to help you learn to use and extend LightSwitch. The introductory materials walk you through the Visual Studio LightSwitch product. By following the hands-on labs, you'll build an application to inventory a library of books.
The more advanced materials will show developers how they can extend LightSwitch to make components available to the LightSwitch developer. In the advanced hands-on labs, you will build and package an extension that can be reused by the Visual Studio LightSwitch end user.
