Please note that we no longer sell Microsoft Visual Studio LightSwitch.

Information from Visual Studio LightSwitch Team Blog

"Visual Studio 2015 is the last release of Visual Studio that includes the LightSwitch tooling and we recommend users not begin new application development with LightSwitch. That said, we will continue to support users with existing LightSwitch applications, including critical bug fixes and security issues as per the Microsoft Support Lifecycle. For reference, the mainstream support phase for Visual Studio 2015 is active until 10/13/2020."
