What NuGet packages are required for this skill?

You need to install Microsoft.Extensions.DependencyInjection and Microsoft.Extensions.Hosting (version 9.0.0 or later recommended).

Why is the Service Locator pattern discouraged?

The Service Locator is considered an anti-pattern because it hides class dependencies, makes code harder to maintain, and complicates unit testing compared to Constructor Injection.

Does it support different service lifetimes?

Yes, it provides guidance on using Singleton for global state, Scoped for request-based logic, and Transient for short-lived instances like ViewModels.

Can I use this for WPF desktop applications?

Yes, this skill includes specific patterns for integrating GenericHost into App.xaml.cs and using constructor injection for ViewModels and Windows.

Desarrollo de API

Configures .NET Dependency Injection and GenericHost to implement professional IoC patterns in console and WPF applications.

Acerca de

This Claude Code skill provides specialized guidance for implementing Dependency Injection (DI) using the standard Microsoft.Extensions.DependencyInjection library and GenericHost. It helps developers set up service containers, manage service lifetimes (Singleton, Scoped, Transient), and apply best practices like constructor injection while avoiding anti-patterns like the Service Locator. Ideal for modernizing WPF applications or building robust console-based services, this skill ensures clean architecture and testable code within the .NET ecosystem.
