Dependency Injection

Package: DesignPatterns.Extensions.DependencyInjection

Overview

Optional Microsoft.Extensions.DependencyInjection integration. Does not replace container lifetime rules — it registers generated registries and resolves implementations from IServiceProvider.

Manual registration

Extension methods such as:

• AddStrategyRegistry<TKey, TStrategy>(...)
• AddFactoryRegistry<TKey, TProduct>(...)
• AddHandlerPipeline<TContext>(...)

Generated RegisterDi

When the DI package (or its MSBuild targets) is referenced, Strategy / Factory / Handler generators can emit:

PaymentStrategyRegistry.RegisterDi(services);

Handlers and strategies resolve from DI; registries register as singletons by default (see sample for transient factory behavior).

Project setup

Reference DesignPatterns.Extensions.DependencyInjection and import its targets (see package / sibling project build/DesignPatterns.Extensions.DependencyInjection.targets).

Set DesignPatternsSampleKind=DependencyInjection in sample projects for the shared MSBuild imports in DesignPatterns.Samples.

Sample

DesignPatterns.Samples.DependencyInjection

Note on meta package

The core Skymly.DesignPatterns NuGet meta package does not include the DI extension; reference DesignPatterns.Extensions.DependencyInjection from the main repo (sibling project) until a separate package is published.
