Entity Framework Core

Entity Framework Core (EF Core) is a cross-platform version of Microsoft Entity Framework that is one of the most popular object-relational mappers (ORMs).

ORM is a technique that helps you to query and manipulate data as per required business output. Refer to the discussion at https://stackoverflow.com/questions/1279613/what-is-an-orm-and-where-can-i-learn-more-about-it for more details.

EF Core supports various databases. A complete list of databases is available here: https://docs.microsoft.com/en-us/ef/core/providers/index. The current version of EF Core is 2.0.
