Как спроецировать из `Dictionary<A, B>` в `Dictionary<A,C>` с помощью AutoMapper?

У меня довольно простая настройка AutoMapper, в которой я хочу сопоставить IDictionary<Guid, From> с Dictionary<Guid, To>. Это отлично работает с IMapper.Map, но мне действительно хочется использовать IQueryable.ProjectTo. Однако это приводит к следующему сбою теста:

using System;
using System.Collections.Generic;
using System.Linq;
using AutoMapper;
using AutoMapper.QueryableExtensions;
using Xunit;

public class AutoMapperTests()
{
    private readonly IMapper mapper = new MapperConfiguration(
        (cfg) =>
        {
            cfg.CreateMap<From, To>();
        }
    ).CreateMapper();

    [Fact]
    public void AutoMapperConfigurationIsValid() =>
        mapper.ConfigurationProvider.AssertConfigurationIsValid();

    [Fact]
    public void CanMapFromDictToDict()
    {
        var key = Guid.NewGuid();
        var fromDict = CreateFromDict(key, key.ToString());

        var toDict = new[] { fromDict }
            .AsEnumerable()
            .Select(it => mapper.Map<IDictionary<Guid, To>>(fromDict))
            .Single();

        Assert.Single(toDict);
        Assert.True(toDict.ContainsKey(key));
        Assert.True(toDict[key].Id == key.ToString());
    }

    [Fact]
    public void CanProjectFromDictToDict()
    {
        var key = Guid.NewGuid();
        var fromDict = CreateFromDict(key, key.ToString());

        var toDict = new[] { fromDict }
            .AsQueryable()
            .ProjectTo<IDictionary<Guid, To>>(mapper.ConfigurationProvider)
            .Single();

        Assert.Single(toDict);
        Assert.True(toDict.ContainsKey(key));
        Assert.True(toDict[key].Id == key.ToString());
    }

    private IDictionary<Guid, From> CreateFromDict(Guid key, string id) =>
        new Dictionary<Guid, From>
        {
            {
                key,
                new() { Id = id }
            }
        };

    public class From
    {
        public required string Id { get; set; }
    }

    public class To
    {
        public required string Id { get; set; }
    }
}

Добавление запрошенного сопоставления приводит к сбою всех тестов:

    private readonly IMapper mapper = new MapperConfiguration(
        (cfg) =>
        {
            cfg.CreateMap<From, To>();
            cfg.CreateMap<IDictionary<Guid, From>, IDictionary<Guid, To>>();
        }
    ).CreateMapper();

Как заставить проекцию работать?

@LucianBargaoanu спросил, «[...] это вообще возможно в EF Core без оценки клиента?». Поэтому я добавил следующий тестовый пример, который проходит нормально.

    [Fact]
    public void CanProjectManuallyFromDictToDict()
    {
        var key = Guid.NewGuid();
        var fromDict = CreateFromDict(key, key.ToString());

        var toDict = new[] { fromDict }
            .AsQueryable()
            .Select(it => fromDict.ToDictionary(it => it.Key, it => new To { Id = it.Value.Id }))
            .Single();

        Assert.Single(toDict);
        Assert.True(toDict.ContainsKey(key));
        Assert.True(toDict[key].Id == key.ToString());
    }
