ILifetimeScope.ResolveNamed ComponentNotRegisteredException

我将ILifetimeScope传递给类ctor，目的是通过名称和接口类型解析已注册的类型。名称存储在数据库中，可以是5种或6种类型中的一种。例如：

public interface ISomeInterface
{
    Task SomeTask();
}
public class TypeA : ISomeInterface
{
    public async Task SomeTask()
    {
        await Task.Yield();
    }
}
public class TypeB : ISomeInterface
{
    public async Task SomeTask()
    {
        await Task.Delay(1000);
    }
}
public class SomeExecutor()
{
    private readonly ILifetimeScope _scope;
    public SomeExecutor(ILifetimeScope scope)
    {
        _scope = scope;
    }
    public async Task RunAsync(string type)
    {
        var class = _scope.ResolveNamed<ISomeInterface>(type); // This throws the exception.
        await class.SomeTask();
    }
}
public static class Program()
{
    static void Main()
    {
        var builder = new ContainerBuilder();
        builder.RegisterType<SomeExecutor>();
        builder.RegisterAssemblyTypes(typeof(ISomeInterface).Assembly)
            .Where(x => typeof(ISomeInterface.IsAssignableFrom(x))
            .AsImplementedInterfaces()
            .AsSelf(); // Taken from Autofac docs.
        var container = builder.Build();
        var executor = container.Resolve<SomeExecutor>();
        executor.RunAsync("TypeA").Wait();
    }
}

抛出的异常是

请求的服务"TypeA（ISomeInterface）"尚未注册。若要避免此异常，请注册一个组件以提供服务，使用IsRegistered（）检查服务注册，或者使用ResolveOption（）方法解析可选依赖项。

我按照错误的建议进行了检查，检查了IsRegistered(typeof(ISomeInterface))和IsRegistered(typeof(TypeA))，结果都是True。

我已经进行了一些运行时调试，并验证了_scope.ComponentRegistry.Registrations中存在该类型，但我注意到该特定类型的范围是CurrentScopeLifetime，而其他一些类型是RootScopeLifetime。我不确定这是否有任何意义。

我尝试过以几种不同的方式注册ISomeInterface，例如

builder.RegisterAssemblyTypes(typeof(ISomeInterface).Assembly)
    .Where(x => typeof(ISomeInterface.IsAssignableFrom(x))
    .AsSelf();
builder.RegisterAssemblyTypes(typeof(ISomeInterface).Assembly)
    .Where(x => typeof(ISomeInterface.IsAssignableFrom(x))
    .As<ISomeInterface>();
builder.RegisterAssemblyTypes(typeof(ISomeInterface).Assembly)
    .Where(x => typeof(ISomeInterface.IsAssignableFrom(x))
    .As<ISomeInterface>()
    .AsSelf();
builder.RegisterAssemblyTypes(typeof(ISomeInterface).Assembly)
    .Where(x => typeof(ISomeInterface.IsAssignableFrom(x))
    .AsImplementedInterfaces()
    .AsSelf()
    .AssignableTo<ISomeInterface>();

可能还有我能想到的其他组合。

我的问题是，我做错了什么，无法通过名称和接口解析类型？

builder.RegisterAssemblyTypes(typeof(ISomeInterface).Assembly)
    .Where(x => typeof(ISomeInterface).IsAssignableFrom(x))
    .AsImplementedInterfaces()
    .AsSelf().Named<ISomeInterface>(x => x.Name);

public class SomeExecutor
{
    private readonly ILifetimeScope _scope;
    public SomeExecutor(ILifetimeScope scope)
    {
        _scope = scope;
    }
    public async Task RunAsync<T>() where T:ISomeInterface
    {
        var tt = _scope.Resolve<T>(); 
        await  tt.SomeTask();
    }
}
static void Main(string[] args)
{
        var builder = new ContainerBuilder();
        builder.RegisterType<SomeExecutor>();
        builder.RegisterAssemblyTypes(typeof(ISomeInterface).Assembly)
            .Where(x => typeof(ISomeInterface).IsAssignableFrom(x))
            .AsImplementedInterfaces()
            .AsSelf();
        var container = builder.Build();
        var executor = container.Resolve<SomeExecutor>();
        executor.RunAsync<TypeA>().Wait();
    }
