public partial class Tag
{
    [Key]
    [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
    public int Id { get; set; }
    public string Name { get; set; }
    public string Description { get; set; }
}

HomeController.cs 类:

public async Task<IActionResult> Index()
{
   tagRepository.Insert(new Tag 
               { 
                   Name = "name", 
                   Description = "description" 
               });
   await UnitOfWork.SaveChangesAsync();  // calls dbContext.SaveChangesAsync()

   return View();
}

TagRepository.cs 类:

    // Context it's a usual DBContext injected via Repository's constructor
    public virtual void Insert(TEntity item)
