Working with Data in LightSwitch (Guided Tour)

Applications that you build in Visual Studio LightSwitch use a "forms over data" model. Forms, which are called screens in LightSwitch, are used to display, enter, or update data that is stored in a database or other data source. In this set of lessons you will learn how to connect to a data source; modify the data types that are used to display data; validate data; define relationships between data sources; and much more.

Note

This lesson builds upon the My First Application project that you created in the Creating Your First LightSwitch application lesson. If it is not already open, open it by pointing to File, and then clicking Open Project
