Microsoft has announced a new product called Microsoft Visual Studio LightSwitch, which the company claims is the simplest way to build business applications for the desktop and cloud. LightSwitch is a new member of the Visual Studio family focused on making it easy to develop line-of-business applications. Jason Zander, corporate vice president for Visual Studio at Microsoft, says, at their core, "most end-user business applications combine two things: data plus screens." LightSwitch is optimized around making these two things very simple. LightSwitch is a tool which allows you to create Line of Business (LoB) applications by using a visual tool, similar to Microsoft Access, although LightSwitch can also produce applications for the web and can pull data from various sources instead of its own build-in database.
