Ado.net实体框架，用于oracle 12c标识列

是否有办法告诉实体框架列是标识符，并自动设置storegeneratedpattern= identity ?手动操作有点问题

public partial class EDUCATIONGROUPS 
{ 
    public EDUCATIONGROUPS() { this.EDUCATIONGROUP_EDUCATION = new HashSet<EDUCATIONGROUP_EDUCATION>(); } 
    public int EDUCATIONGROUP_ID { get; set; } 
    public string NAME { get; set; } 
    public System.DateTime MODIFIEDTIME { get; set; } 
    public string MODIFIEDBY { get; set; } 
    public virtual ICollection<EDUCATIONGROUP_EDUCATION> EDUCATIONGROUP_EDUCATION { get; set; } 
}

首先创建数据库
