使用實體框架自動生成控制器/模型時出錯-Web.Config

Question

我在從代碼優先實體框架自動生成的視圖中遇到問題。 我相信我的數據庫有問題，但我無法解決。

我正在嘗試使用BoringBar.cs類進行此初始化，但是對於所有類我都遇到相同的錯誤。 這是BoringBar.cs類。

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; }
 }
}

這也是我正在使用的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; }

  }
}

這是我的web.config文件，用於定義連接。

我已經准備好嘗試從app_Data刪除遷移文件夾和數據庫，然后成功遷移數據庫。 連接設置/數據庫設置是否有問題？ 它正在尋找什么元數據？

Answer 1

我不得不注釋掉

<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中的實體6.0中的錯誤。對VS 2015的升級也對其進行了修復。
