存储将对象列表作为属性的对象，而不让这些对象生成单独的表

问：

我有这个具有 2 个复杂属性的类：

public class App
{
    [Key]
    public Guid Id { get; set; }
    public string StringId { get; set; } = string.Empty;
    public string AppName { get; set; } = string.Empty;
    public Guid WorkspaceId { get; set; }
    public List<FieldStructure> Fields { get; set; } = new List<FieldStructure>();
    public List<FieldStructureRelation> RelationFields { get; set; } = new List<FieldStructureRelation>();
}

这些是所谓的属性对象：

[Owned]
public class FieldStructure
{
    public FieldStructure(string name, string type)
    {
            Name = name;
            Type = type;
            NameAsProperty = name.ToLower().Replace(" ", "_");
            
    }

    public FieldStructure() { }

    public string Name { get; set; } = string.Empty;
    public string NameAsProperty { get; set; } = string.Empty;
    public string Type { get; set; } = string.Empty;

}
[Owned]
public class FieldStructureRelation : FieldStructure
{
    public FieldStructureRelation(FieldStructure fieldStructure, string appRelationId) 
        : base(fieldStructure.Name, fieldStructure.Type)
    {
        this.AppRelationId = appRelationId;
    }

    public FieldStructureRelation(string name, string type, string appRelationId) 
        : base(name, type) 
    {
        this.AppRelationId = appRelationId;
    }
        
    public FieldStructureRelation() { }

    public string AppRelationId { get; set; } = string.Empty;
}

我想要的只是将这些属性存储在我的应用程序表中的列中，而不是存储在单独的表中......也许作为JSON对象？

我以为在我的 dbcontext 中这样做就足够了，但是不，它会不断生成表并且不显示我的应用程序中的属性：

modelBuilder.Entity<App>()
    .OwnsMany(app => app.Fields, fields =>
    {
        fields.Property(c => c.Type);
        fields.Property(c => c.Name);
        fields.Property(c => c.NameAsProperty);
    });
modelBuilder.Entity<App>()
    .OwnsMany(app => app.RelationFields, rFields =>
    {
        rFields.Property(c => c.Type);
        rFields.Property(c => c.Name);
        rFields.Property(c => c.NameAsProperty);
        rFields.Property(c => c.AppRelationId);
    });

我觉得这应该是一件非常简单的事情，但我看不到正确的方法。提前致谢！
