What Is Entity Framework Core?

Entity Framework Core Tutorial: A Complete Guide for Developers

Entity Framework Core (EF Core) is a modern, open-source, object-database mapper for .NET. Whether you're building enterprise-grade software or a quick prototype, EF Core lets you interact with your database using .NET objects, eliminating the need to write complex SQL manually.

This comprehensive tutorial will take you from the basics to advanced usage patterns, including setup, modeling, migrations, querying, and performance optimization.

📌 What Is Entity Framework Core?

Entity Framework Core is an ORM (Object-Relational Mapper) that sits between your .NET application and your relational database. It allows you to:

• Map .NET classes to database tables
• Perform CRUD operations without writing raw SQL
• Use LINQ to query data
• Work with multiple database providers (SQL Server, PostgreSQL, SQLite, etc.)

EF Core is the cross-platform rewrite of the original Entity Framework. It supports both code-first and database-first approaches and is optimized for performance and flexibility.
