Lightswitch Users & Roles & ApplicationDatabase

I can see that the internal database for lightswitch is called "ApplicationDatabase" and if you look inside the directory structure outside of Vs10 the database is in the bin folder.

Is anyone aware of how I would extend the users and roles function in lightswitch? I need to be able to associate which "store" a user belon开发者_开发问答gs to so that when they authenticate I can pass in the store parameter to the queries I have created.

LightSwitch uses the same Membership framework that is used by ASP.NET and other Microsoft technologies. I've written this blog post on the topic of how to link data to user logins; this should hopefully get you started on this topic.
