This course introduces Entity Framework Core for data access and object-relational mapping. Entity Framework Core provides benefits such as the ability to work with databases using .NET objects without the concern for underlying database tables. This leads to less code for data access and improved performance. 

You’ll begin with the workflows of Entity Framework Core—reverse engineering and migrations. Next, you’ll learn model configuration and relationships. Then, you’ll cover various methods for querying and saving data. You’ll also learn about change tracking and its relationship with queries. Finally, you’ll learn about logging and testing.

Entity Framework Core simplifies app development. By the end of this course, you’ll be able to improve code maintainability and concentrate on business logic by generating SQL, materializing results, and performing other tasks. You’ll have a good understanding of Entity Framework Core, which will improve your productivity and efficiency on your development journey.

Using Entity Framework Core for Data Access & Relational Mapping

## Overview
In this lesson, we’ll review strategies for loading related entities via the navigational properties of entities in EF Core. There are three common patterns:

- Eager loading
- Explicit loading
- Lazy loading

The differences between these patterns are related to how and when EF Core translates the queries to the database.

## Eager loading
**Eager loading** loads related data from the database as part of the initial query. It allows us to fetch related entities and prevent additional round-trips to the database. Eager loading uses the `Include` method to specify the related data.

We’ll demonstrate eager loading using the C# console project below:
