Although no coding is required LightSwitch does allow you to customize screen layouts and add custom business logic.
If you have Visual Studio 2010 already installed then LightSwitch will be installed into the existing Visual Studio IDE as a new project type. One thing to be aware of is that if you have Visual Studio 2010 already installed then you’ll need to be sure to upgrade to the Visual Studio 2010 SP1 before installing LightSwitch beta 2.
