Create Database inside the project Create a normal project (form, console, wpf, class-library) ‘right click’ on project add -> new item -> data-> service-based database … name it

Create tables In the project : add -> new item -> data -> ADO.NET Entity Data Model … name it choose ‘empty model’ In diagram ‘right click’ -> add new -> entity (=table) Fill out entity name (= table name) Fill out property for primary key (default id:int) Add more properties/columns one by one – remember type ‘right click’ generate database from model – pick (connect to ) your database
