20 Essential Entity Framework Core Tips: Optimize Performance, Streamline Queries, and Enhance Data Handling

Learn how to boost query performance, operations, and manage large datasets effectively. From basic to advanced tips for developers looking to enhance their EF Core skills.

1. Use AsNoTracking for Read-Only Scenarios

AsNoTracking fetches data that is not intended to be changed in the current context. It makes queries faster and more efficient because EF Core does not need to capture tracking information.

var users = context.Users.AsNoTracking().ToList();

The aforementioned query retrieves all users from the database without any tracking overhead, which provides performance gain in data-heavy application

2. Opt for Explicit Loading

Explicit loading is a process where related data is loaded from the database at a later time and not immediately with the initial query.

var book = context.Books.Single(b => b.BookId == 1);
context.Entry(book).Collection(b => b.Authors).Load();
