Developer project created by Microsoft Visual Studio development software; used for saving LightSwitch projects, which are used for creating business applications without having to write much source code.
LightSwitch projects are comprised of "data entities" and "screens." Data entities provide the model for representing data and screens provide the user interface elements for how the application displays data.
NOTE: LightSwitch projects are also created by Visual Studio LightSwitch 2011. However, LightSwitch projects created with Visual Studio 2012 are not backward compatible with Visual Studio LightSwitch 2011.
