实体框架不在数据库中创建表

Question

I've just started to learn ASP.Net MVC and Entity Framework using some tutorial and I have a problem.

I created class for Database Connection OdeToFoodDb.cs

using System;
using System.Collections.Generic;
using System.Data.Entity;
using System.Linq;
using System.Web;

namespace OdeToFood.Models
{
    public class OdeToFoodDb : DbContext
    {
        public DbSet<Restaurant> Restaurants { get; set; }
        public DbSet<RestaurantReview> Reviews { get; set; }
    }
}

and two classes Restaurant.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace OdeToFood.Models
{
    public class Restaurant
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public string City { get; set; }
        public string Country { get; set; }
        public ICollection<RestaurantReview> Review { get; set; }
    }
}

and RestaurantReview.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace OdeToFood.Models
{
    public class RestaurantReview
    {
        public int Id { get; set; }
        public int Rating { get; set; }
        public string Body { get; set; }
        public int RestaurantId { get; set; }
    }
}

Then I try Add Connection

And I've got database but it doesn't contain tables RestaurantReviews or Restaurants

but my tutorial says that I get these tables automatically. What I did wrong? How to make it create tables I need?

Answer 1

In your Package Manager Console, run the following command

Update-Database -ProjectName <YourProject.DataLayer>

Check if your connection string is pointing to your expected database
