What are the differences between Code First and Database First approaches in Entity Framework, and when would you choose one over the other?

Differences Between Code First and Database First in Entity Framework

In Entity Framework, the Code First approach involves defining your data model using C# or VB.NET classes first, and then generating the database schema based on those classes. This approach allows for greater control over the database structure and relationships.

On the other hand, the Database First approach involves creating the data model by reverse-engineering an existing database. This approach is suitable when working with legacy databases or when the database structure is already defined and needs to be integrated into the application.

When to Choose Code First vs. Database First

Choosing between Code First and Database First depends on the project requirements and preferences. If you want more control over the database design and relationships, Code First is the way to go. It is also well-suited for projects where the database schema needs to be maintained along with the codebase.

On the other hand, if you are working with an existing database and need to quickly integrate it into your application without changing the schema, Database First is a better choice. It is also useful when working with legacy databases or when the database design is already established.
