What problem does it solve?

This Skill helps developers understand and apply idiomatic C# and .NET patterns, improving code quality, maintainability, and performance.

Core Features & Use Cases

  • Idiomatic C# Usage: Guidance on immutability, explicit over implicit, and dependency injection.
  • Async/Await Patterns: Best practices for asynchronous programming in .NET.
  • Options Pattern: Bind configuration sections to strongly-typed objects for safer configuration management.
  • Result Pattern: Return explicit success/failure instead of throwing exceptions.
  • Repository Pattern: Implementation with EF Core for database operations.
  • Minimal API Patterns: Organizing APIs for better maintainability and performance.
  • Guard Clauses: Early returns with clear validation for more readable code.
  • Anti-Patterns: Identifying and avoiding common pitfalls in .NET development.
  • Use Case: Use this Skill when designing and implementing .NET applications to follow best practices and avoid common mistakes.

Quick Start

Review the 'Prefer Immutability' section to understand best practices for creating immutable data models in C#.

Frequently Asked Questions about dotnet-patterns

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
What is the Result pattern in C# and how does it handle errors?

The Result pattern in C# returns explicit success or failure states instead of throwing exceptions. This approach improves code readability and debuggability by forcing developers to handle errors immediately without relying on exception handling for control flow.

How do I implement the Repository pattern with EF Core in .NET?

Implement the Repository pattern with EF Core by creating abstraction classes for database operations. This organizes data access logic centrally, ensuring maintainable APIs and testable code while avoiding direct DbContext injection into business logic layers.

What are common async/await anti-patterns in .NET applications?

Common async/await anti-patterns in .NET include blocking on asynchronous code with .Result and using async void methods. Identifying these pitfalls early ensures robust applications by preventing deadlocks and unobserved task exceptions during asynchronous programming.

How do I use the Options pattern for configuration in .NET?

The Options pattern in .NET binds configuration sections to strongly-typed objects. This provides safer configuration management by validating settings at startup, preventing runtime errors caused by missing or malformed configuration values in your application.

Why prefer immutability and explicit over implicit in C#?

Preferring immutability and explicit over implicit in C# creates predictable data models and clear execution paths. This idiomatic usage reduces side effects and hidden behaviors, significantly improving application maintainability and performance.

How do I organize Minimal APIs in .NET for better maintainability?

Organize Minimal APIs in .NET by applying guard clauses for early returns and grouping endpoints logically. This pattern ensures better maintainability and performance by keeping validation explicit and avoiding deeply nested conditional logic.
