Does HTML 5 Herald The End Of RIA Plug-Ins? Not Really
Will HTML 5 make rich Internet application (RIA) technologies such as Adobe Flash/Flex and Microsoft Silverlight obsolete? For at least the next five years, the answer is a definite “no”; inconsistent implementations of the draft HTML 5 specification and immature tooling make building HTML 5 apps that work consistently across browsers and operating systems a real challenge. Furthermore, this “either/ or” scenario is driven only by vendor politics, not by developer realities.

ADO.NET in Disconnected Mode
You see how ADO.NET differs from its predecessor when you start working in disconnected mode.

As a matter of fact, working in disconnected mode is the most scalable technique you can adopt because it takes resources on the client (instead of on the server) and, above all, it doesn”t enforce any locks on database tables (except for the short-lived locks that are created during the update operation).
