使用实体框架自动生成控制器/模型时出错-Web.Config

Question

我在从代码优先实体框架自动生成的视图中遇到问题。 我相信我的数据库有问题，但我无法解决。

我正在尝试使用BoringBar.cs类进行此初始化，但是对于所有类我都遇到相同的错误。 这是BoringBar.cs类。

using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.ComponentModel.DataAnnotations.Schema;
using System.Linq;
using System.Web;


namespace SetupSheet.Models.CollectionofTool
 {
  [Table("BoringBar")]
  public class BoringBar : Tool
  {
    [Required]
    [Display(Name = "Boring Bar Diameter")]
    public double BarDiameter { get; set; }

    [Required]
    [Display(Name = "Minimum Hole Diameter for Bar Clearance")]
    public double MinimumHoleDiameter { get; set; }

    [Required]
    public double Radius { get; set; }

    [Required]
    [Display(Name = "Maximum Z Depth")]
    public double MaximumZDepth { get; set; }

    [Required]
    [Display(Name = "Lead Angle")]
    public double LeadAngle { get; set; }
 }
}

这也是我正在使用的DbContext文件Datamodel.cs。

using System;
using System.Collections.Generic;
using System.Data.Entity;
using System.Linq;
using System.Web;
using SetupSheet.Models;
using SetupSheet.Models.CollectionofTool;
using SetupSheet.Models.CollectionofRawMaterial;
using Microsoft.AspNet.Identity.EntityFramework;

namespace SetupSheet.Models
{

public class DataModel : IdentityDbContext<ApplicationUser>
{
    public DataModel()
        : base("DefaultConnection")
    {
    }
    public DbSet<SetupSheet> SetupSheets { get; set; }
    public DbSet<Tool> Tools { get; set; }
    public DbSet<TurningTool> TurningTools { get; set; }
    public DbSet<BoringBar> BoringBars { get; set; }
    public DbSet<IDGroover> IDGroovers { get; set; }
    public DbSet<ODGroover> ODGroovers { get; set; }
    public DbSet<PartingTool> PartingTools { get; set; }
    public DbSet<Drill> Drills { get; set; }
    public DbSet<IDThreader> IDThreaders { get; set; }
    public DbSet<ODThreader> ODThreaders { get; set; }
    public DbSet<Endmill> Endmills { get; set; }
    public DbSet<Stop> Stops { get; set; }
    public DbSet<Reamer> Reamers { get; set; }
    public DbSet<RawMaterial> RawMaterials { get; set; }
    public DbSet<Round> Rounds { get; set; }
    public DbSet<Square> Squares { get; set; }
    public DbSet<Sheet> Sheets { get; set; }
    public DbSet<Hexagonal> Hexagonals { get; set; }
    public DbSet<Tube> Tubes { get; set; }
    public DbSet<Transaction> Transactions { get; set; }

  }
}

这是我的web.config文件，用于定义连接。

我已经准备好尝试从app_Data删除迁移文件夹和数据库，然后成功迁移数据库。 连接设置/数据库设置是否有问题？ 它正在寻找什么元数据？

Answer 1

我不得不注释掉

<add name="DefaultConnection" providerName="System.Data.SqlClient" connectionString="Data Source=(LocalDb)\v11.0;Initial Catalog=aspnet-MvcApplication1-20160306200318;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\aspnet-MvcApplication1-20160306200318.mdf"

在web.config文件中。 它和VS 2013中的实体6.0中的错误。对VS 2015的升级也对其进行了修复。
