LINQ Projection and Grouping in Entity Framework Core

When building modern applications, fetching entire database rows can slow down performance and waste network bandwidth. Learning how to shape and group your data directly within your database queries is essential for building fast, scalable applications. This written course teaches you how to leverage Language Integrated Query (LINQ) in Entity Framework Core to extract and group exactly the data your application needs. You will transition from writing basic database queries to crafting sophisticated, optimized projection and grouping operations. First, you will build a solid foundation by understanding how the Entity Framework Core query pipeline works under the hood. Then, you will progress to transforming query results into custom shapes and aggregating complex datasets efficiently. What you'll learn: - Understand the core concepts of the Entity Framework Core query execution pipeline - Project database entities into custom anonymous types and strongly-typed Data Transfer Objects (DTOs) - Group related data collections using LINQ grouping operations to perform server-side aggregations - Apply modern C# features like records and required properties to secure and clean up your data structures - Optimize query performance by minimizing data transfer and avoiding common database round-trip pitfalls - Implement conditional logic and nested projection patterns within your database queries This course begins with foundational database querying concepts and essential LINQ terminology before moving into practical, step-by-step query construction. You will read clear explanations, analyze real-world code snippets, and study optimized query patterns. This course is designed for beginner C# developers and database learners who want to improve their data retrieval skills. No prior experience with advanced query optimization is required.
