Whilst researching for my next Dot Net project, a desktop LightSwitch application, I discovered a number of resources relating to LightSwitch. LightSwitch is a free RAD tool for versions of Visual Studio. Visual Studio Professional or above is required - see http://www.microsoft.com/en-us/download/details.aspx?displaylang=en&id=26830
The Microsoft page for LightSwitch is at http://msdn.microsoft.com/en-us/vstudio/ff796201
There are introductory videos at http://blogs.msdn.com/b/bethmassi/archive/2011/12/01/beginning-lightswitch-getting-started.aspx
APress have a good book, Visual Studio LightSwitch 2012, at http://www.apress.com/9781430250715
Pluralsight have an excellent course on Visual Studio LightSwitch 2012 and 2013 at http://pluralsight.com/training/courses/TableOfContents?courseName=visual-studio-lightswitch2012
I am currently working through this excellent course.
Regrettably, LightSwitch is only available in Visual Studio Professional and higher. For further details, please see the discussion at http://social.msdn.microsoft.com/Forums/vstudio/en-US/8de34d50-df83-4c17-9946-b2d01e73b14c/is-lightswitch-available-for-visual-studio-2013-express?forum=lightswitch
