Microsoft released the first beta of the Visual Studio LightSwitch IDE earlier this week. It’s designed to allow non-programmers create business applications and allow programmers of various levels to create applications quickly. It simplifies the process and allows doing many common functions like coding a database interaction to be done from a visual perspective. If you need to code anything, you can choose between Visual Basic .NET or C#. The overall goal seems to be allowing one to focus on the business rules and policies while creating an app, not the syntax.
For a quick (a minute and a half) look at Visual Studio LightSwitch, you can watch this video Microsoft has created.
For a walkthrough of building a first application with LightSwitch, you can find step-by-step instructions with this article on a MSDN blog by Jason Zanders.
To download the beta and find more videos, you can visit the official Microsoft Visual Studio LightSwitch site. You will also find more resources at the MSDN LightSwitch Developer Center.
