Async Container Build

VContainer executes pre-processing such as reflection when building a container. To reduce main thread blocking time for your game:

Set false to LifetimeScope.autoRun
After scene loading, Call LifetimeScope.Build manually.

For example:

var nextScene = await LoadSceneAsync(...);

var lifetimeScope = LifetimeScope.Find<MyLifetimeScope>(nextScene.Scene);

// Your async solution here.
await UniTask.Run(() => lifetimeScope.Build());

⚠️ Unity dependent features such as builder.RegisterComponentInHierarcky() do not work on background threads.

If this causes an error, use Awake instead.

For example:

class GameLifetimeScope : LifetimeScope
{
    Ground groundInScene;

    protected override void Awake()
    {
        // Run main thread.
        groundInScene = FindObjectOfType<Ground>();

        base.Awake();
    }

    protected override void Configure(IContainerBuilder builder)
    {
        // It can run background thread.
        builder.RegisterInstance(groundInScene);
    }
}
