Visual Studio LightSwitch is a tool that's designed to let power users build data-centric business applications for the desktop and cloud. The tooling takes care of code generation, data access and common infrastructure needs, allowing the application builder to focus on business logic. If enhanced functionality is required, developers can extend the application with custom .NET code. In terms of data access, LightSwitch applications can use many data sources including SharePoint 2010 list data. The tooling uses a combination of the client object model and the REST API, so the integration is rich and powerful. In this session, you'll see how to build LightSwitch applications that use data from SharePoint 2010.
