SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill standardizes and streamlines dependency injection configuration in C# projects, reducing boilerplate and helping teams maintain clean registrations and lifecycles.

Core Features & Use Cases

  • Centralized DI configuration for Startup/Program.cs, with clear lifecycle management (Transient/Scoped/Singleton).
  • Factory-based registrations and third-party container integration (e.g., Autofac) to support advanced scenarios.
  • Provide templates and patterns for batch registration and consistent service wiring across projects.

Quick Start

Use the di-config-expert skill to guide you through setting up DI in a new or existing C# project by following the examples in SKILL.md. The body after frontmatter will be loaded as instructions during activation.

FAQPage Schema
How do I configure dependency injection in C# Startup or Program.cs?

To configure dependency injection in C# Startup or Program.cs, you register services with clear lifecycle management (Transient, Scoped, or Singleton) to reduce boilerplate and maintain clean service wiring across the application.

When should I use factory-based registrations in .NET dependency injection?

Use factory-based registrations in .NET dependency injection to support advanced scenarios where you need custom object construction logic or third-party container integration, ensuring services are resolved correctly based on runtime conditions.

Can I use Autofac or other third-party DI containers with .NET service registrations?

Yes, you can integrate third-party DI containers like Autofac with .NET service registrations by applying factory-based patterns and container integration to support advanced dependency resolution beyond the default provider.

What is the best way to manage service lifecycles across a C# application?

The best way to manage service lifecycles in a C# application is through centralized DI configuration, applying Transient, Scoped, or Singleton patterns consistently during Startup to prevent captive dependencies and memory leaks.

How do I batch register services to reduce DI boilerplate in C#?

You can batch register services to reduce DI boilerplate in C# by applying centralized configuration templates and patterns, which standardize service wiring and lifecycle management across multiple projects.

Why does my dependency injection configuration fail when resolving scoped services?

Dependency injection configuration fails resolving scoped services when lifecycles are mismatched, such as injecting a Scoped service into a Singleton; centralized DI configuration helps manage and validate these lifecycle constraints properly.
