DryIoc ScopedTo 现在包括父作用域？

Question

下面的代码适用于 DryIoc 2.x。我刚刚更新到 4.x。该代码不再有效（请参阅下面的例外情况）。似乎 4.x 将“ScopedTo”数据视为非排他性的，而在 2.x 中，它们是范围独有的——它们不可用于开箱即用的其他范围。我现在如何获得 2.x 行为？异常列出了几种补救措施，但哪种补救措施符合 2.x 行为？

using System;
using DryIoc;

namespace TestDryIoc
{
    public interface IDep {}

    public interface IOwner
    {
        IDep Dep { get; }
    }
    
    public class Dep1: IDep {}
    public class Dep2: IDep {}

    public class Owner1: IOwner
    {
        public Owner1(IDep dep)
        {
            Dep = dep;
        }
        
        public IDep Dep { get; }
    }

    public class Owner2: IOwner
    {
        public Owner2(IDep dep)
        {
            Dep = dep;
        }
        
        public IDep Dep { get; }
    }
    
    class Program
    {
        static void Main(string[] args)
        {
            var container = new Container();
            container.Register<IDep, Dep1>(Reuse.InResolutionScopeOf<Owner1>());
            container.Register<IDep, Dep2>(Reuse.InResolutionScopeOf<Owner2>());
            
            container.RegisterMany<Owner1>(Reuse.Singleton, setup: Setup.With(openResolutionScope: true));
            container.RegisterMany<Owner2>(Reuse.Singleton, setup: Setup.With(openResolutionScope: true));

            container.Resolve<Owner2>();
        }
    }
}

我在 v4.2.3 中得到的异常：

DryIoc.ContainerException: code: ExpectedSingleDefaultFactory; message: Expecting single default registration but found many:

Answer 1

似乎是一个错误。我在 DryIoc 存储库 https://github.com/dadhi/DryIoc/issues/290 中创建了相应的问题。请把讨论移到那里。

只有 Reuse.Singleton 父服务才会出现此问题。因此，在问题得到解决之前，解决方法可能是更改 Owner 重用或插入人工作用域以扮演这些服务的单例角色。

更新

带有修复程序的 DryIoc v4.2.4 已在 NuGet 上发布 https://github.com/dadhi/DryIoc/releases/tag/v4.2.4

DryIoc ScopedTo 现在包括父作用域？

DryIoc ScopedTo now includes parent scope?
