  • What is Entity Framework (EF)?

    Entity Framework is an Object-Relational Mapping (ORM) framework developed by Microsoft. It enables developers to interact with databases using .NET objects, abstracting the underlying database interactions and providing a higher-level, object-oriented interface.

  • How does Entity Framework perform Object-Relational Mapping?

    Entity Framework performs Object-Relational Mapping by mapping database tables to .NET classes and database records to instances of those classes. It provides a set of APIs and tools for developers to work with database entities using familiar object-oriented programming concepts.

  • What are Code-First and Database-First approaches in Entity Framework?

    Code-First: Developers define the data model using .NET classes, and the database schema is generated based on these classes.
    Database-First: Developers start with an existing database, and Entity Framework generates .NET classes based on the database schema.

  • What is the DbContext in Entity Framework?

    The DbContext is a core component in Entity Framework that represents a session with the database. It is responsible for coordinating Entity Framework functionality, such as managing database connections, tracking changes, and executing queries.

  • How does Entity Framework handle migrations?

    Entity Framework Migrations is a feature that enables developers to evolve the database schema over time. It allows the automatic generation of scripts to update the database schema based on changes in the model, ensuring seamless database schema evolution with code changes.
