我可以将影子财产用于财产孩子吗？

Question

我正在尝试使用新的EF Core Shadow属性进行服务器端分页，列表结果的排序和过滤。

排序和分页效果很好，除了我想按实体子属性UserName对列进行排序时。有没有一种方法可以使用阴影属性按属性子属性进行排序？
像这样的东西：.OrderBy(p => EF.Property<object>(p, "user.UserName"))

实体模型：

public class Player
{
    public int Id { get; set; }
    public int UserId { get; set; }
    public int GamePlayed { get; set; }
    public int GameWon { get; set; }
    public int Rank { get; set; }
    public DateTime LastPlayedDate { get; set; }
    public DateTime JoinDate { get; set; }
    public bool Active { get; set; }
    public virtual User User { get; set; }
}

public class User
{
    public int Id { get; set; }
    public string UserName { get; set; }
    public string Email { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public string Description { get; set; }
}

查询：

public IEnumerable<Player> GetPlayers(string colName, string filter,
        string sortOrder, int pageNumber, int pageSize)
    {
        var skip = pageNumber * pageSize;

        var results = (sortOrder == "asc") ?
            _context.Players.Where(p => p.Active)
            .OrderBy(p => EF.Property<object>(p, colName))
            .Skip(skip).Take(pageSize)
            .Include(p => p.User)
            :
            _context.Players.Where(p => p.Active)
            .OrderByDescending(p => EF.Property<object>(p, colName))
            .Skip(skip).Take(pageSize)
            .Include(p => p.User);

        return results;
    }
