We've just uploaded the updated version of the Extensibility Toolkit to the MSDN Extensions Gallery: LightSwitch Extensibility Toolkit for VS11

The toolkit provides project types for creating new LightSwitch Extension Libraries that target Visual Studio 11 and includes templates for creating the following LightSwitch extensions: LightSwitch Business Type, LightSwitch Control, LightSwitch Data Source, LightSwitch Screen Template, LightSwitch Shell, and LightSwitch Theme.

Updated versions of the eight extensibility samples have been uploaded to the LightSwitch Extensibility Samples for VS 11 as well.

Enjoy!
