ArdysaModsTools uses Microsoft.Extensions.DependencyInjection for all service resolution.

Register All Services

csharp

using ArdysaModsTools.Core.DependencyInjection;
using Microsoft.Extensions.DependencyInjection;

var services = new ServiceCollection();
services.AddArdysaServices();

var provider = services.BuildServiceProvider();

Service Categories

AddArdysaServices() registers everything. Individual categories can also be registered separately:

csharp

services
    .AddCoreServices()       // ModInstaller, Status, ActiveMods, Detection, Config, FileTransaction
    .AddConflictServices()   // ConflictDetector, ConflictResolver, ModPriority
    .AddHeroServices()       // HeroGeneration
    .AddLoggingServices()    // Logger (NullLogger default)
    .AddPresenters()         // ModOperations, Patch, Navigation presenters
    .AddUIFactories();       // MainForm factory

Resolve Services

csharp

// Core services
var installer = provider.GetRequiredService<IModInstallerService>();
var status = provider.GetRequiredService<IStatusService>();
var activeMods = provider.GetRequiredService<IActiveModsService>();
var detection = provider.GetRequiredService<IDetectionService>();
var config = provider.GetRequiredService<IConfigService>();

// Hero generation
var heroGen = provider.GetRequiredService<IHeroGenerationService>();

// Conflict handling
var detector = provider.GetRequiredService<IConflictDetector>();
var resolver = provider.GetRequiredService<IConflictResolver>();

Service Lifetimes

Service	Lifetime	Reason
`IModInstallerService`	Transient	Each operation gets fresh state
`IStatusService`	Transient	Disposable (timer + file watcher)
`IActiveModsService`	Transient	Stateless query service
`IDetectionService`	Transient	Fresh detection each call
`IConfigService`	Singleton	Shared config state
`IConflictDetector`	Singleton	Stateless, reusable
`IAppLogger`	Singleton	Single logger instance

Replace Logger

The default is NullLogger. Replace with a real logger:

csharp

var services = new ServiceCollection();
services.AddArdysaServices();

// Override with real logger
services.AddSingleton<IAppLogger>(new Logger(richTextBoxConsole));

var provider = services.BuildServiceProvider();
