C# 找不到实体类型HierarchyId的合适构造函数

我在DotnetCore3.1中工作，需要使用层次结构，我必须在表中使用HierarchyId，我首先使用代码。但当我尝试执行添加迁移时，它返回以下错误：

未找到实体类型“HierarchyId”的合适构造函数。以下构造函数的参数无法绑定到实体类型的属性：无法绑定“HierarchyId（SqlHierarchyId value）”中的“value”

这是我的实体类

public class MyHClass
{
    public int Id { get; set; }
    [Required]
    public string Name { get; set; }
    public HierarchyId Level { get; set; }
}

这是我的上下文类，在添加MyHClass worlds之前，它会正确地查找表并将表添加到数据库中

public class ArtiDbContext : IdentityDbContext<IdentityUser>
{
    public ArtiDbContext(DbContextOptions<MyDbContext> options)
        : base(options)
    {

    }

    public new DbSet<T> Set<T>() where T : BaseEntity
    {
        return base.Set<T>();
    }

    public DbSet<SampleEntity> SampleEntity { get; set; }
    public DbSet<MyHClass> MyHClasses { get; set; }

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {

        base.OnModelCreating(modelBuilder);

    }
}

公共类ArtiDbContext:IdentityDbContext
{
公共ArtiDbContext（DbContextOptions）
：基本（选项）
{
}
public new DbSet Set（），其中T:BaseEntity
{
返回base.Set（）；
}
公共DbSet SampleEntity{get；set；}
公共DbSet MyHClasses{get；set；}
模型创建时受保护的覆盖无效（ModelBuilder ModelBuilder）
{
基于模型创建（modelBuilder）；
}
}

这是我安装的软件包：

<PackageReference Include="EntityFrameworkCore.SqlServer.HierarchyId" Version="1.0.0" />
<PackageReference Include="Microsoft.EntityFrameworkCore" Version="3.1.4" />
<PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" Version="3.1.4" />
<PackageReference Include="Microsoft.EntityFrameworkCore.Tools" Version="3.1.4">

有关更多信息，我也将整个错误放在这里：
