I personally feel that upcoming VS.Net version will going to be really cool. You will find lot of features out of box to quickly get you started for development. This release will going to be for those, who wants to write less code and do rapid development with less code maintenance.
VS.Net 2013 Preview feature list:
- Responsive Design using Twitter Bootstrap
- Scaffolding available for Asp.net web forms, mvc and web api projects.
- Improvement to existing way of external authentication (Google, Twitter, FB, etc...)
- Mobile switcher for asp.net application
- One Asp.net - You can mix asp.net web form, mvc, web api other technologies to serve your needs.
- And many more... Please note I didn't get chance to explore all.
