Data Access with Code First EF Core

Building scalable applications requires a solid database foundation, yet mapping object-oriented code to relational databases can often feel like a disconnect. This text-based course guides you through the process of defining, configuring, and maintaining your database schema directly from your C# code. You will transition from manual database management to a modern, code-first workflow that integrates smoothly with your application logic. By reading through clear explanations and structured code snippets, you will learn how to model complex data relationships and safely update your database structure as your application evolves. We start with foundational definitions, ensuring you understand the core mechanics of the Entity Framework Core DbContext and model configuration before moving on to hands-on implementation. What you'll learn: - Understand the core concepts of Entity Framework Core and the DbContext lifecycle - Configure entity relationships including one-to-many and complex many-to-many associations - Apply data annotations and Fluent API configurations to define precise schema constraints - Manage database schema changes safely using EF Core migrations and CLI tools - Implement modern C# features like nullable reference types to write safer database code - Practice generating, applying, and rolling back database migrations in a local environment This course begins with essential database mapping terminology and basic configuration patterns. From there, you will progress to handling advanced relationship configurations and managing production-ready schema migrations. This course is designed for beginner to intermediate C# developers who want to learn database modeling. No prior database administration or advanced ORM experience is required.
