Introduction of LightSwitch

Microsoft Visual Studio LightSwitch is a development environment designed to simplify and shorten the development of typical forms-over-data applications for businesses. Regardless of your development skills—whether you’re a beginner or an experienced developer—LightSwitch enables you to quickly create professional-quality business applications. And you can do so without writing a line of code.

In most business applications, developers spend a large amount of time:

·         Writing code to interact with a data source

·         Creating a user interface

·         Writing code to specify the business logic

With LightSwitch, your application can point to an existing data source—or databases that are automatically created—without the need to write code. For the user interface, LightSwitch provides screens that are based on predefined templates. They allow you to display data automatically by simply specifying which elements you want to show.

For the business logic, LightSwitch allows you to do simple validation such as required fields and minimum numeric values. But LightSwitch also gives developers the ability to write more complex business logic code for such scenarios as saving changes to a data source or performing authorization operations.
