实体框架在发布模式下避免使用[NotMapped]属性 [英] Entity Framework avoiding [NotMapped] attribute in release mode

问题描述

我最近将我的项目从4.0升级到了.NET Framework 4.5。完成本

到目前为止，我已经尝试过：

1. 从关于类似问题的其他答案中，我尝试删除了引用 System.ComponentModel.DataAnnotations; 在上述文件中-无效




2. 尝试复制 .dll 路径中的文件

     C：\WINDOWS\Microsoft.Net\ assembly\GAC_MSIL\System.ComponentModel.DataAnnotations\v4.0_4.0.0.0__31bf3856ad364e35\System.ComponentModel.DataAnnotations.dll ** 
     

   到应用程序的 bin 目录




3. 已更新使用Update-Package安装的 NuGet软件包-重新安装-Project Kyc v4

以上都不适合我，并且如果您想知道-我的 DbContext 错误中提到的模型没有 DbSet 推测是 [NotMapped] 属性由于某种原因被实体框架（ 6.1.3 ）忽略。我的 System.ComponentModel.DataAnnotations 参考中的版本为 4.0.0.0 ，运行时为 v4.0.30319

我们非常感谢您的帮助。谢谢

解决方案

最后，我发现问题出在 Visual Studio IDE中本身。由于某种原因，它在执行 Clean / Build或 Rebuild时没有清除旧的引用，因此这些引用发生冲突并与 System.ComponentModel.DataAnnotations.Schema 。因此，我手动删除了旧文件并发布到了一个新的空目录。

I have recently upgraded my project to .NET Framework 4.5 from 4.0. After completing all tasks mentioned in this MSDN Migration Guide, I added some changes to the models for supporting Oracle database.

The models are shown here:

namespace KYC_v4.Models
{
    [Serializable]
    public class Organization
    {
       public int OrganizationID { get; set; }

       [Required]
       [Display(Name = "OrganizationName", ResourceType = typeof(Resources.Home))]
       [MaxLength(200)]
       public string OrganizationName { get; set; }

       public virtual List<UserGroup> Groups{get;set;}

       public OrganizationDetails Details { get; set; }

       public int UserID { get; set; }

       [NotMapped]
       [MaxLength(100)]
       public string membersCount { get; set; }

       [NotMapped]
       public List<CheckOrgPermissionViewModel> CheckPermission { get; set; }
    }
}

public class CheckOrgPermissionViewModel {
    public string Permissiontype { get; set; }
    public bool isTrue { get; set; }
}

It is running normally when I debug from Visual Studio, but when I try to host it in IIS server, I get this error:

What I have tried so far:

1. From other answers about similar issues, I tried to remove the reference System.ComponentModel.DataAnnotations; in the above files - did not work

2. Tried copying the .dll file from the path

   C:\WINDOWS\Microsoft.Net\assembly\GAC_MSIL\System.ComponentModel.DataAnnotations\v4.0_4.0.0.0__31bf3856ad364e35\System.ComponentModel.DataAnnotations.dll**
   

   to the bin directory of the application

3. Updated the installed NuGet packages using Update-Package -reinstall -Project "Kyc v4"

None of the above works for me, and if you are wondering - I do not have the DbSet for the models mentioned in the error in my DbContext, so my guess is the [NotMapped] attribute is being ignored by Entity Framework (6.1.3) for some reason. The version in my System.ComponentModel.DataAnnotations reference is 4.0.0.0 and runtime is given as v4.0.30319

Any help is appreciated. Thank you

解决方案

In the end, I have found out that the issue was with the Visual studio IDE itself. It was not cleaning the old references while doing "Clean"/"Build" or "Rebuild" for some reason so the references were conflicting and causing confusion with the System.ComponentModel.DataAnnotations.Schema. So I manually deleted the old files and published to a new empty directory.
