2. Entity Framework Core is an object-relational mapper (ORM) that
bridges the gap between your C# code and the commands required to
access relational databases. EF Core automatically maps your classes
and code to the tables and views of a database, making it much easier
to query and write to databases from a .NET application.
It’s never been more important to master Entity Framework Core.

3. Entity Framework Core in Action, Second Edition is an in-depth guide to
reading and writing databases with EF Core. Revised from the
bestselling original edition, it’s filled with over 100 diagrams, code
snippets, and examples—including a project in which you build and
scale your own bookselling web application.

4. Fully updated and upgraded with
new content, new diagrams, and
new examples, this second
edition of the bestselling original
begins with a clear breakdown of
Entity Framework Core, along
with the mental model behind
ORM.
You’ll discover time-saving
patterns and best practices for
security, performance tuning,
unit testing, and much more!
