Scenario: You are developing an application that needs to interact with a SQL Server database. Which component of Entity Framework would you use to define the data model and work with the database?

DbContext serves as the primary class in Entity Framework for interacting with the database. It represents a session with the database and can be used to query and save instances of your entities. It also allows you to define the data model through entity classes and their relationships. DbSet, on the other hand, represents a collection of entities of a specific type in the context. Entity Data Model is a conceptual model that describes the structure of data, but DbContext is the component used to interact with the database. Code-First Approach is a methodology for creating the data model through code rather than using a visual designer, but DbContext is the component that enables this approach within Entity Framework.
