如何在EF核心代码中转换存储在json字段中的嵌套对象

public class NestedObject
{
    public string Name { get; set; }
    public int Age { get; set; }
}

using Microsoft.EntityFrameworkCore;
using Microsoft.EntityFrameworkCore.Storage.ValueConversion;

public class MyEntity
{
    public int Id { get; set; }
    public string NestedJson { get; set; }

    [NotMapped]
    public NestedObject NestedObject
    {
        get => JsonConvert.DeserializeObject<NestedObject>(NestedJson);
        set => NestedJson = JsonConvert.SerializeObject(value);
    }
}

public class MyDbContext : DbContext
{
    public DbSet<MyEntity> MyEntities { get; set; }

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        var converter = new ValueConverter<NestedObject, string>(
            v => JsonConvert.SerializeObject(v),
            v => JsonConvert.DeserializeObject<NestedObject>(v));

        modelBuilder.Entity<MyEntity>()
            .Property(e => e.NestedJson)
            .HasConversion(converter);
    }
}
