点这里进入ABP入门教程目录 

创建实体

在领域层(即JD.CRS.Core)下新建文件夹Entitys //用以存放实体对象
添加一个实体类Course.cs //课程信息

using Abp.Domain.Entities;
using Abp.Domain.Entities.Auditing;
using Abp.Timing;
using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.ComponentModel.DataAnnotations.Schema;

namespace JD.CRS.Entitys
