Efcore Patterns

What it does

The efcore-patterns skill provides guidance on best practices and common patterns for using Entity Framework Core in .NET applications. It helps developers implement efficient data access, manage relationships between entities, and optimize queries using established design patterns.

When to use it

• You're designing a new data model with Entity Framework Core and need guidance on structuring your entities.
• You want to improve the performance of existing EF Core queries by applying known optimization techniques.
• You’re working on a team and need consistent practices for handling database operations in .NET applications.
• You're refactoring legacy code that uses raw SQL or inefficient data access patterns.

Key capabilities

• Explains common design patterns like repository, unit of work, and query object.
• Provides examples of how to configure EF Core for different scenarios.
• Offers advice on handling relationships, lazy loading, and eager loading.
• Covers best practices for query optimization and avoiding N+1 issues.

Example prompts

• "How can I implement the repository pattern with Entity Framework Core?"
• "What are some common patterns for optimizing LINQ queries in EF Core?"
• "Can you explain how to handle one-to-many relationships using EF Core?"

Tips & gotchas

• Ensure your project is targeting .NET 6 or later, as many modern EF Core patterns rely on newer features.
• Some advanced patterns may require additional libraries or custom implementations, so review the documentation for compatibility.
