Added DbContext Generator

以下课程是为我的课程（课程，讲座，学生）创建的，名为＆＃34;管理＆＃34;：

public class Management
    {
        public class Course
        {

            public int CourseId { get; set; }
            public string CourseName { get; set; }
            public string Description { get; set; } 
            public ICollection<Student> Students { get; set; }
            public ICollection<Lecture> Lectures { get; set; }
        }
        public class Lecture
        {

            public int LectureId { get; set; }
            public String LectureName { get; set; }
            public String Description { get; set; }
            public int CourseId { get; set; }
            [System.ComponentModel.DataAnnotations.Schema.ForeignKey("CourseId")]
            public virtual Course Course { get; set; }
        }
        public class Student
        {

            public int StudentId { get; set; }
            public String FirstName { get; set; }
            public String LastName { get; set; }
            public int CourseId { get; set; }
            [System.ComponentModel.DataAnnotations.Schema.ForeignKey("CourseId")]
            public virtual Course Course { get; set; }
        }
    }  

在软件包管理器控制台中：

PM> Scaffold Controller Management

我收到以下错误：

Get-PrimaryKey : Cannot find primary key property for type 'RBS.PFM.Models.Management'. No properties appear to be primary keys.
At C:\Projects\RBS Project\RBS.PFM\packages\MvcScaffolding.1.0.9\tools\Controller\MvcScaffolding.Controller.ps1:71 char:15

    + CategoryInfo          : NotSpecified: (:) [Get-PrimaryKey], Exception

任何人都可以建议解决此问题的最佳方法。
