How does Entity Framework handle database schema changes in a Code-First approach?
- Entity Framework automatically updates the database schema without requiring any manual intervention from developers.
- Entity Framework generates a new database schema from scratch with each change, discarding existing data.
- Entity Framework generates migration files that represent incremental changes to the database schemDevelopers can apply these migrations to update the database schema without losing data.
- Entity Framework prompts developers to manually update the database schema by executing SQL scripts.
In a Code-First approach with Entity Framework, database schema changes are managed through migrations. When developers modify the application's data model, Entity Framework generates migration files that represent these changes. Developers can then apply these migrations to update the database schema incrementally. Entity Framework tracks the history of migrations applied to the database, allowing developers to roll back changes if needed. This approach enables developers to evolve the database schema alongside the application's data model while preserving existing data.
