How to Connect to a SQL Server Database Using LightSwitch Visual Studio 2012

How to Connect to Data

In LightSwitch, we can easily connect to existing data or to data tables that we create.

To provide data to a LightSwitch application, we can either connect to an existing data source such as a SQL Server database, or we can create tables in the SQL Server Express database that is included in LightSwitch.

We can connect to data by connecting:

  • through a SQL Server Database
  • to a SharePoint List
  • to an Open Data (OData) Service
  • to a Windows Communication Foundation (WCF) Rich Internet Application (RIA) Service

We can then use this data to create screens and queries in Visual Studio LightSwitch 2012.
