Defining Code First EF Core Model
Explore how to define a Code First data model in Entity Framework Core, including setting up many-to-many relationships and generating databases during development. Learn the basics of data annotations, schema creation, and understand EF Core migrations and inheritance mapping strategies to maintain and evolve your database models.
Implementing Code-First development in EF Core
Sometimes, we will not have an existing database. Instead, we define the EF Core model as Code First, and then EF Core can generate a matching database using create and drop APIs.
Note: The create and drop APIs should only be used during development. Once we release the app, we do not want it to delete a production database.
Example
