以OrganizationUnit為例，進行擴展，加入IsUse屬性
1.創建一個新類，比如ExtendedOrganizationUnit，繼承OrganizationUnit

public class ExtendedOrganizationUnit: OrganizationUnit
{
    public bool IsUse { get; set; }
}

2.把ExtendedOrganizationUnit添加到DbContext裏

public virtual DbSet<ExtendedOrganizationUnit> ExtendedOrganizationUnits { get; set; }
 

3.使用ef code first遷移命令

add-migration add_ExtendedOrganizationUnit_table
update-database

成功
