The entity type Blog is not part of the model for the current context.

今天在写代码的时候报如下错误：

The entity type Blog is not part of the model for the current context.

截图如下：

代码如下：

using System.Data.Entity;
using AppDAL.Entity;

namespace AppDAL.Model
{
    public class AppContext:DbContext
    {
        public AppContext()
            : base("name=BlogAppConn")
        { }

        
    }
}

using System;
using System.ComponentModel;
using System.ComponentModel.DataAnnotations;

namespace AppDAL.Entity
{
    public partial class Blog
    {       
        public int Id { get; set; }

        [Required]
        [StringLength(500)]
        [DisplayName("标题")]
        public string Title { get; set; }

        [Required]
        [DisplayName("正文")]
        public string Body { get; set; }
        [DisplayName("创建时间")]
        public DateTime CreationTime { get; set; }
        [DisplayName("更新时间")]
        public DateTime UpdateTime { get; set; }
        [DisplayName("选择类别")]
        public int CategoryId { get; set; }
        [DisplayName("作者")]
        public int AuthorId { get; set; }
        public int ArchivesId { get; set; }
        [DisplayName("专题页面")]
        public bool Topics { get; set; }
    }
}

解决方案：

using System.Data.Entity;
using AppDAL.Entity;

namespace AppDAL.Model
{
    public class AppContext:DbContext
    {
        public AppContext()
            : base("name=BlogAppConn")
        { }

        public DbSet<Blog> Blogs { get; set; }
    }
}
