Suggested Answer: Explanation 🗳️
Using the Entity Framework, developers issue queries using LINQ, then retrieve and manipulate data as strongly typed objects.
From scenario: The children's book area of the web application must get data directly from a local database. It must use a connection string. It must also support access to the stored procedures on a database. Further, it is required to have strongly typed objects. Finally, it will require access to databases from multiple vendors and needs to support more than one-to-one mapping of database tables.
