SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps developers correctly implement and leverage the Microsoft.Extensions stack, avoiding common pitfalls in dependency injection, configuration, logging, and more, ensuring robust and maintainable .NET applications.

Core Features & Use Cases

  • Dependency Injection: Correctly register and resolve services with appropriate lifetimes.
  • Configuration Management: Bind and validate application settings effectively.
  • Logging: Implement structured and efficient logging practices.
  • HttpClientFactory: Utilize IHttpClientFactory for reliable HTTP communication.
  • Hosted Services: Build and manage background tasks within the .NET Generic Host.
  • Use Case: When building a new ASP.NET Core application, ensure all services are registered correctly, configuration is validated at startup, and background tasks are implemented using BackgroundService for proper lifecycle management.

Quick Start

Use the dotnet-microsoft-extensions skill to correctly wire up dependency injection for a new ASP.NET Core web API.

FAQPage Schema
How do I correctly register services with appropriate lifetimes in .NET dependency injection?

Correctly registering .NET dependency injection services requires matching service lifetimes to avoid captive dependencies. This Skill guides proper service registration and resolution to ensure robust and maintainable application infrastructure.

What is the best way to bind and validate application configuration in ASP.NET Core?

The best way to bind and validate ASP.NET Core configuration is using the Microsoft.Extensions configuration stack at application startup. This Skill helps you effectively bind settings and validate configuration to fail fast and ensure maintainability.

Why should I use IHttpClientFactory instead of directly instantiating HttpClient in .NET?

You should use IHttpClientFactory instead of directly instantiating HttpClient to avoid socket exhaustion and manage handler lifetimes. This Skill provides reliable HTTP communication patterns utilizing the Microsoft.Extensions stack for robust .NET applications.

How do I implement background tasks within the .NET Generic Host?

To implement background tasks within the .NET Generic Host, use the BackgroundService pattern for proper lifecycle management. This Skill covers building and managing hosted services to ensure your application robustness and maintainability.

How does structured logging work in ASP.NET Core applications?

Structured logging in ASP.NET Core works by capturing logged events as key-value pairs rather than plain text. This Skill helps implement structured and efficient logging practices using the Microsoft.Extensions stack for maintainable .NET applications.

When do I need to use the Microsoft.Extensions stack for my .NET application?

You need the Microsoft.Extensions stack when building ASP.NET Core applications requiring dependency injection, configuration management, structured logging, or hosted services. This Skill ensures correct implementation and avoids common pitfalls for robust infrastructure.
