使用Entity Framework Core迁移更改主键 [英] Changing Primary Key using Entity Framework Core Migrations

问题描述

我试图通过Entity Framework Core Migrations更改表的主键：

I am trying to Change the Primary key of a table via Entity Framework Core Migrations:

protected override void Up(MigrationBuilder migrationBuilder)
{
        migrationBuilder.DropPrimaryKey(
            name: "PK_Permissions",
            table: "Permissions");
}

当我尝试更新数据库时，出现以下错误消息：

When I try to update the database I get the following error message:

To change the IDENTITY property of a column, the column needs to be dropped and recreated.

如何更新数据库？
