I want to rewrite a whole classic ASP website to new technology. But I don't want to change our current SQL Server database.

Which is the best new technology and language that more efficient, more secure, more robust, develop more quickly and relevant with our old classic ASP?

  1. I prefer C# , MVC, JavaScript and etc.
  2. Must run on all OS and mobile view.
  3. Also I prefer disconnected mode.
