What problem does it solve?

This Skill helps you optimize LINQ queries and EF Core data access, eliminating common performance bottlenecks like N+1 queries and inefficient data loading. It ensures your ABP applications are fast, responsive, and minimize database load.

Core Features & Use Cases

• N+1 Query Prevention: Provides solutions using eager loading (Include), projections (Select), and batch loading to drastically reduce database round trips.
• Efficient Data Loading: Guides on using AsNoTracking for read-only scenarios and AsSplitQuery to prevent Cartesian explosion with multiple collections.
• Optimized Pagination & Filtering: Demonstrates cursor-based and optimized offset pagination, along with ABP's WhereIf extension for dynamic filtering.
• Use Case: A backend developer identifies a slow API endpoint caused by N+1 queries. Using this skill, they refactor the data access layer to use projections and eager loading, reducing the endpoint's response time from seconds to milliseconds.

Quick Start

Refactor a LINQ query that fetches a list of 'Doctors' and their 'Appointments' to prevent N+1 issues using eager loading with Include.
