Visual Studio LightSwitch is a powerful environment that makes it easier for developers to build modern, high-quality business applications. One great benefit is that you use the same approach even with different data sources, ignoring what happens behind the scenes, and you use the same screen templates regardless of the data source that will be bound to the user interface.
To provide this great level of flexibility and abstraction, the LightSwitch team has worked very hard. After all, it was necessary to take different .NET technologies and integrate them to build an architecture that allows three tiers in an application to be abstract from one another but also to communicate with one another in an efficient way. So, you have an easy way to build applications, but also a robust application infrastructure based on complex architecture.
