You implement an Entity Data Model and then run the Create Database Wizard. You need to complete the steps to create a database that you can use with your entity classes.

What should you do?

Create Database Wizard does not execute the generated Data Definition Language (DDL). To create the database schema that corresponds to your conceptual model, you must execute the generated DDL independently (for example, execute the DDL in SQL Server Management Studio).

You do not need to select the Run Custom Tool item for all project templates to regenerate code. This will not create the database.
