插入后,计算出的主键不会在EF核心实体中更新

我有一个特殊情况,表的ID被定义为这样的计算列:

CREATE TABLE [BusinessArea](
    [Id]  AS (isnull((CONVERT([nvarchar],[CasaId],(0))+'-')+CONVERT([nvarchar],[ConfigurationId],(0)),'-')) PERSISTED NOT NULL,
    [CasaId] [int] NOT NULL,
    [ConfigurationId] [int] NOT NULL,
    [Code] [nvarchar](4) NOT NULL,
    [Name] [nvarchar](50) NOT NULL,
 CONSTRAINT [PK_BusinessArea] PRIMARY KEY CLUSTERED 
(
    [Id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON, FILLFACTOR = 80) ON [PRIMARY]
) ON [PRIMARY]
GO

通常当我有一个计算列时,我会这样配置它:

builder.Entity<MyEntity>()
 .Property(p => p.MyComputed).HasComputedColumnSql(null);

用 .HasComputedColumnSql() mycomputed的值反映了对实体的插入/更新。

但是,如果计算列是一个pk,这个技巧就不起作用。

你知道如何使它也能与pk一起工作吗?
