Entity Framework is an ORM tool. ORM means Object Relational Mapping. ORM tool automatically creates classes based on the database tables. ORM also generates the SQL for database tables.

To know about the main usage of Entity Framework, see the below example. If wanted to display the combination of two tables as one table and if the normal method is followed instead of Entity Framework, then follow the below steps.
