Generate child scope with code first

Child can also be generated from your C# code.
class LevelLoader
{
    readonly LifetimeScope currentScope;

    LifetimeScope instantScope;

    public LevelLoader(LifetimeScope lifetimeScope)
    {
        currentScope = lifetimeScope;
    }

    public void Load()
    {
        // ... Loading some assets with any async way you like
        //
        // await Addressables.LoadAssetAsync...
        //

        // Create a child scope for the container that contains this LevelLoader instance.
        instantScope = currentScope.CreateChild();

        // Create with LifetimeScope prefab
        instantScope = currentScope.CreateChildFromPrefab(
            lifetimeScopePrefab);

        // Create with LifetimeScope prefab and extra registrations
        instantScope = currentScope.CreateChildFromPrefab(
            lifetimeScopePrefab, builder =>
            {
                builder.RegisterInstance(someExtraAsset);
                builder.RegisterEntryPoint<ExtraEntryPoint>(Lifetime.Scoped);
                // ...
            });

        // Create a child scope with extra registrations
        instantScope = currentScope.CreateChild(builder =>
        {
            // ...
        });

        // Create a child scope with extra registrations via `IInstaller`
        instantScope = currentScope.CreateChild(extraInstaller);


        // The additionally registered entry point runs immediately after the scope is created...

        // Or you can use scoped instance directly.
        var foo = instantScope.Container.Resolve<Foo>();
    }

    public void Unload()
    {
        // Note that the scope implicitly create `LifetimeScope`.
        // Use `Dispose` to safely destroying the scope.
        instantScope.Dispose();

        // ... Unloading some assets
    }
