Database Migrations — ASP.NET MVC 4 includes the new Entity Framework 4.3 release, which includes a bunch of great new features. One of the most eagerly anticipated features it provides is database migration support. This enables you to easily evolve your database schema using a code focused migration approach — and do so while preserving the data within your database. I’ll blog more about this in the future – you can also see a walkthrough of database migrations in this tutorial.
Mobile Web — ASP.NET MVC 4 includes new support for building mobile web applications and mobile web sites, and makes it much easier to build experiences that are optimized for phone and tablet experiences. It includes jQuery Mobile, and includes new support for customizing which view templates are used depending upon what type of device is accessing the app. See the ASP.NET MVC 4 tutorial series.
Razor Enhancements — ASP.NET MVC 4 includes V2 of our Razor View engine. Razor V2 includes a bunch of juicy enhancements that enable you to make your view templates even cleaner and more concise — including better support for resolving URL references and selectively rendering HTML attributes.
