无法使用实体框架创建控制器-无法检索元数据 [英] Cannot create controller with Entity framework - Unable to retrieve metadata

问题描述

我正在使用VS2013

当我尝试创建带有使用实体框架的视图的MVC 5控制器" 时，出现以下错误:

When I try to create an "MVC 5 Controller with views using entity Framework" I get the following error:

there was an error running the selected code generator ''Unable to retrieve metadata for WebApplication.Domain.Entities.Product'.'

EFDbContext.cs

using System.Data.Entity;
using WebApplication.Domain.Entities;

namespace WebApplication.Domain.Concrete
{
    public class EFDbContext : DbContext
    {
        public DbSet<Product> Products;
    }
}

Product.cs

using System.ComponentModel.DataAnnotations;

namespace WebApplication.Domain.Entities
{
    public class Product
    {
        [Key]
        public int ProductID { get; set; }

        [Required]
        public string Title { get; set; }
    }
}

Web.config

<?xml version="1.0" encoding="utf-8"?>

    </providers>
  </entityFramework>
</configuration>

我有一个名为Products的表格，其定义如下:

I have a Table set up called Products and it has a definition like so:

CREATE TABLE [dbo].[Products] (
    [ProductID] INT            IDENTITY (1, 1) NOT NULL,
    [Title]     NVARCHAR (255) NULL,
    PRIMARY KEY CLUSTERED ([ProductID] ASC)
);

任何想法出了什么问题?我已经尝试了所有在Google上返回的内容.

Any ideas what is going wrong? I have tried everything that has returned on Google.

我已安装的软件包:

<?xml version="1.0" encoding="utf-8"?>
<packages>
  <package id="EntityFramework" version="6.0.1" targetFramework="net45" />
  <package id="jQuery" version="1.10.2" targetFramework="net45" />

推荐答案

public class EFDbContext : DbContext
{
    public DbSet<Product> Products { get; set; }
}

忘记了{get;放;} ...现在所有作品都可以#crying

Forgot the { get; set; }... all works now #crying
