When it comes to integrating with cloud-based applications, there is one player that generally comes to mind first, and that would be Google. There is a demo version of a Google Data extension from RSSBus available from the Visual Studio LightSwitch gallery. We’ll use this extension to show how easy it is to connect to literally any Google data source.

For this last example, we’re going to build a simple tool that will query for calendar events and then give you the option of adding the event to a Google calendar. With the RSSBus extension, you simply add a new data source and choose their provider (see Figure 5-11).
