BoatRental Made a testdriven console application with SQLServer database and EntityFramework. You got four projects in the Solution. BoatRental -PROJECT Console application -Program.cs (classes) -Admin.cs -Rental.cs BookingBoatSystem -Library PROJECT -Booking.cs BookingBoatSystemTests -Test PROJECT -BookingTests.cs Data -Entityframework PROJECT Download and restore the databasefile: BoatBookingSystem.bak All projects got an App.config with a connection string. 3. I hope the database will work good and that you don't need to change the connectionString.
