Problems with registration and injection of an orchestrator with scene lifetimeScope implementing the IStartable interface.

[srodriguezf]

Good afternoon,

I have a global LifetimeScope in this registry with the following line a global orchestrator.

builder.RegisterEntryPoint(Lifetime.Singleton).As().WithParameter("initializationServiceOrder", GlobalServicesInitializationList.SceneInitializationOrder);

This orchestrator I inject it and it works perfectly. Class definition:

public class GlobalOrchestrator : IStartable, IGlobalOrchestrator

Further on, I have a scene lifetimeScope and I register a scene orchestrator as follows:

builder.RegisterEntryPoint().As().WithParameter("initializationPluginOrder", PluginInitializationList.SceneInitializationOrder);

Both the global orchestrator and the scene orchestrator implement the IStartable interface.

When trying to inject it into a scene service of the same LifetimeScope the following error occurs:

Any idea why when I inject the orchestrator I get this error with respect to the registration?

[tigran-sargsyan-w]

You’re injecting a Scene EntryPoint (IStartable) into services of the same scope. EntryPoints are created/resolved lazily by VContainer during Run and wrapping them in Lazy<> internally. Resolving one from inside the same scope while it’s being created causes the re-entrant Lazy error: “ValueFactory attempted to access the Value property…”.
Don’t inject EntryPoints. Register the orchestrator as a normal service, and use a tiny wrapper EntryPoint to call it.
Fix (safe pattern)

protected override void Configure(IContainerBuilder builder)
{
    // 1) Register the orchestrator as a regular service (inject this everywhere).
    builder.Register<SceneOrchestrator>(Lifetime.Scoped)
           .As<ISceneOrchestrator>();

    // 2) Register a thin EntryPoint that *only* triggers the orchestrator.
    builder.RegisterEntryPoint<SceneOrchestratorStarter>()
           .WithParameter("initializationPluginOrder",
              PluginInitializationList.SceneInitializationOrder);
}

// Your orchestrator no longer implements IStartable.
public interface ISceneOrchestrator
{
    void StartUp();              // or UniTask StartUpAsync()
}

public class SceneOrchestrator : ISceneOrchestrator
{
    public void StartUp()
    {
        // real startup logic here
    }
}

// EntryPoint wrapper that VContainer runs; it depends on the service.
public sealed class SceneOrchestratorStarter : IStartable
{
    private readonly ISceneOrchestrator orchestrator;

    // you can keep your parameter here if needed
    public SceneOrchestratorStarter(
        ISceneOrchestrator orchestrator,
        [Parameter("initializationPluginOrder")] int initOrder)
    {
        this.orchestrator = orchestrator;
    }

    void IStartable.Start()
    {
        orchestrator.StartUp();
        // or await orchestrator.StartUpAsync().Forget();
    }
}

Now:

• Services in the scene inject ISceneOrchestrator safely (no Lazy/re-entrant resolve).
• VContainer creates the starter as the only EntryPoint and calls Start, which then kicks the orchestrator.

Alternative options (if you must keep IStartable on the orchestrator)

• Move the orchestrator to the parent/global scope and inject it into the scene scope only if it has no dependency back into the child scope (avoid cycles).
• Replace direct injection with Func/Lazy and resolve later (e.g., in Start() of a MonoBehaviour). This hides the symptom but the wrapper pattern above is cleaner.

Why this works: EntryPoints are roots (created by the container and invoked by VContainer’s player loop). They should depend on services, not be depended on. Splitting “startup trigger” (EntryPoint) from “orchestrator API” (service) breaks the circular path and removes the re-entrant Lazy access.

I reccomend you read this also: VContainer docs — EntryPoint pattern: https://vcontainer.hadashikick.jp/integrations/entrypoint
