What is the difference between DbContext and ObjectContext in Entity Framework?

In Entity Framework, DbContext and ObjectContext are both important classes that serve as bridge between the application and the database. However, there are some key differences between the two:

DbContext:

• DbContext is a high-level API introduced in Entity Framework 4.1.
• It is optimized for developing code-first approach and supports modern ORM features.
• DbContext represents a combination of the Unit of Work and Repository patterns.
• It is simpler to configure and use compared to ObjectContext.

ObjectContext:

• ObjectContext is a lower-level API that has been around since Entity Framework 1.
• It is designed for use with model-first or database-first approaches.
• ObjectContext represents a traditional Object Relational Mapper (ORM) model.
• It provides more fine-grained control over entity objects and their relationships.

Overall, the main difference between DbContext and ObjectContext lies in their level of abstraction and the development approach they are optimized for. When choosing between the two, developers should consider the specific requirements of their application and the development methodology being followed.
