CSASPNETWebsite is for a Facebook for Websites application, also known as Facebook Connect. These apps are hosted as standalone apps on your server (not iFrames within the Facebook chrome)

CSASPNETFacebookApp is for an "Apps on Facebook" application, also known as a Canvas Application or iFrame application. These apps appear in iFrames on an apps.facebook.com/yourapp URL.

See http://developers.facebook.com/docs/ for more information on what you can do with a canvas vs. connect application.
