我无法在Entity Framework Core中播种数据

Question

我无法将数据植入我的Webapp中，也不知道出了什么问题。该应用程序运行良好，用户可以将数据添加到数据库中。我添加了saveChanges方法，但没有结果。我认为我正在向数据库发送空数据，但是我找不到问题。我的文件：DbContext

 public class BookDbContext: DbContext

{

    public BookDbContext(DbContextOptions options): base(options)

    {

    }

    public DbSet<Books> Books { get; set; }

}

种子书

public static void Initialize(BookDbContext context)

    {

        context.Database.EnsureCreated();

        if (context.Books.Any())

        {

            return;

        }

        var books = new Books[]

         {

        new Books{Id=1, Title ="Kont of Mount Cristos", Description="About eghteen century", Author="Don Mon", Category=Category.aksion},

        new Books{Id=2, Title="Introduction in C Sharp", Description="Learning computer programing", Author="Scott Allen", Category= Category.education},

        new Books{Id=3, Title="The Castle", Description="Learning about history", Author="Ismail Kadare", Category= Category.drama},

        new Books{Id=4, Title="Madam Bavary", Description="Love story", Author="Gi de Mopasan", Category= Category.romance}

         };

        foreach (Books b in books)

        {

            context.Books.Add(b);

        }

            context.SaveChanges();

    }

书籍档案

public enum Category

{

    aksion, drama, romance, education

}

public class Books

{

    public int Id { get; set; }

    [Required]

    public string Title { get; set; }

    [Required]

    [Display(Name = "Autor Name")]

    public string Author { get; set; }

    [MaxLength(80)]

    public string Description { get; set; }

    public Category Category { get; set; }
