SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill streamlines the process of defining and applying complex query logic in .NET applications, making data retrieval more organized, reusable, and testable.

Core Features & Use Cases

  • Reusable Criteria: Define query conditions once and reuse them across different parts of your application.
  • Composability: Combine multiple specifications using logical AND/OR operations.
  • Testability: Isolate and unit test your query logic independently.
  • Use Case: Implement a specification to fetch all active users from a specific organization, including their related orders, and sort them by creation date.

Quick Start

Generate C# code for the Specification pattern, including interfaces, base classes, concrete examples, and repository integration.

FAQPage Schema
How do I implement the specification pattern in C# with Entity Framework Core?▼

Composable query logic lets you combine multiple query specifications using logical AND/OR operations, enabling you to build complex search criteria from smaller, isolated, and testable rule objects.

Why does my Entity Framework Core data access layer become hard to test with complex queries?▼

Complex Entity Framework Core queries become hard to test because logic scatters across repositories, but defining reusable specification criteria isolates query conditions for independent unit testing.

Can I include related entities and apply sorting when using query objects in .NET?▼

Yes, specifications in .NET support includes for eager loading related entities alongside ordering and pagination parameters to handle complex domain model data retrieval efficiently.

What's the best way to organize reusable query logic for complex domain models in .NET?▼

The best way to organize reusable query logic in .NET is using the specification pattern to define query conditions once and compose them across different application parts without duplication.

Does the specification pattern replace the repository pattern in .NET applications?▼

The specification pattern complements the repository pattern in .NET by encapsulating composable query criteria, allowing repositories to remain generic while specifications handle specific entity filtering and includes.
