c# - 附加列不会提交到先前迁移中创建的表

Question

我最初创建了一个包含这些列的表。

我有以下类，它已经由数据库中的迁移创建。

public class Products
{
    [Key]
    public int ProductId { get; set; }

    public string ProductName { get; set; }

    public string ShotDescription { get; set; }

    public decimal OldPrice { get; set; }

    public decimal NewPrice { get; set; }

    public bool DisableBuyButton { get; set; }

    public bool DisableWishListButton { get; set; }

    public bool ShowForPrice { get; set; }


    public bool NotReturnable { get; set; }

    public int MinimumCartQty { get; set; }

    public int MaximumCartQty { get; set; }

    public string SKU { get; set; }


    public bool ShippingEnabled { get; set; }

    public decimal Weight { get; set; }

    public decimal Length { get; set; }

    public decimal Width { get; set; }

    public decimal Height { get; set; }

    public string Categories { get; set; }

    public string ManufacturerPartNumber        { get; set; }

    public DateTime AvailableDate { get; set; }

    public DateTime AvailableEndDate { get; set; }

    public string AdminComment { get; set; }

    public DateTime CreatedOn { get; set; }

    public DateTime UpdatedOn { get; set; }


    public Boolean DisplayAvailability { get; set; }

    public DateTime ExpectedDateBackOnStock { get; set; }

    public bool IsOnBackOrder { get; set; }

    public int Warehouse { get; set; }

    public int BinNumber { get; set; }

    public int IlseNumber { get; set; }



    public bool IsGiftCard { get; set; }

    public bool IsDownloadableProduct { get; set; }

    public bool IsRental { get; set; }


    public string SeoDescription { get; set; }


    public int   Stock { get; set; }

    public int PropertyImageId { get; set; }

}

我使用以下命令创建迁移，然后更新数据库。

Add-Migration InitialCreate

Update-Database

但是，当我向它添加一个新列时，即使它现在在新类中，它也不会将用户 id 列提交到表中，它不会产生任何错误，只是在包管理控制台中说完成但它没有添加列到数据库上的表中。有人可以告诉我我可能做错了什么谢谢。有问题的领域是

公共 Guid 用户 ID { 获取；放; }
