This preview includes: Templated Helpers - allow you to automatically associate edit and display elements with data types. For example, a date picker UI element can be automatically rendered every time data of type System.DateTime is used. Areas - provide a means of dividing a large web application into multiple projects, each of which can be developed in relative isolation. This helps developers manage the complexity of building a large application by providing a way to group related controllers and views. Support for Data Annotations - Data Annotations enable attaching validation logic in a central location via metadata attributes applied directly to a model class.
