EF Code First with Eager Loading and OrderBy

EF (Entity Framework) Code First is a popular ORM (Object-Relational Mapping) framework for .NET that allows you to create database tables and entities from your application code. Eager Loading is a feature that allows you to load related data in one query, while OrderBy allows you to sort the results of a query.

Answer:

EF Code First is a tool for creating database tables and entities from your application code, while Eager Loading is a feature that allows you to load related data in one query. OrderBy is a property of the LINQ query syntax that allows you to sort the results of a query.

EF Code First provides a powerful and flexible way to create and manage database tables and entities. It allows you to define your database schema using code, rather than using a graphical user interface (GUI) tool. This makes it easy to create and modify your database as your application needs change.

Eager Loading is a feature of EF Code First that allows you to load related data in one query, rather than making multiple queries to the database. This can improve the performance of your application by reducing the number of database queries and improving the overall readability of your code.

OrderBy is a property of the LINQ query syntax that allows you to sort the results of a query. This can be useful when you need to display the results of a query in a specific order, such as sorting a list of customers by their name.

EF Code First, Eager Loading, and OrderBy are all related to database development and are commonly used in .NET applications. They provide powerful tools for creating and managing database tables and entities, and can help improve the performance and readability of your code.
