## MVC 6

- ASP.NET MVC and Web API have been merged into one.
- Dependency injection is inbuilt and part of MVC.
- Side by side - deploy the runtime and framework with your application
- Everything packaged with NuGet, Including the .NET runtime itself.
- New JSON based project structure.
- No need to recompile for every change. Just hit save and refresh the browser.
- The compilation is done with the new Roslyn real-time compiler.
- vNext is Open Source via the .NET Foundation and is taking public contributions.
- vNext (and Rosyln) also runs on Mono, on both Mac and Linux today.
