What is Code First?

Code First is a development paradigm, particularly prevalent in object-relational mapping (ORM) systems like Entity Framework, where the database schema is generated from the application's code (typically classes representing data models). Instead of starting with a pre-existing database, developers define the data models in their code, and the ORM framework uses these models to create or update the database schema. This approach emphasizes the application's domain model and simplifies development by allowing developers to work primarily with code, reducing the need to write SQL or directly manage database schema.
