you can add

Database.SetInitializer(new DropCreateDatabaseIfModelChanges<YourDbContext>());

in you r application start . It will recreate database for you if you have modified your configuration. And if you do not want to drop and create database (To incremental development) you can use SqlMigrations. http://www.hanselman.com/blog/EntityFrameworkCodeFirstMigrationsAlphaNuGetPackageOfTheWeek10.aspx
