Before entity Framework, Developer was writing the code Entity Classes which is contains the getter & Setters Method for Data Table Fields (Columns).
what is the purpose of introduce Entity Framework, and what’s different between Entity Framework and Older traditional way to write down Entity Classes?
If you do not use EF (or any other ORM tool), you will have to write both entity classes and related database operations by hand.
ORM tools creates both entity classes and an abstraction of related DB operations automatically.
In case of EF, it creates entity classes and an
ObjectContext(or aDBContext) which allows you to manipulate DB entities without writing SQL code.
