升级.NET Framework 4.5的应用程序 - 无法获取正确的DataAnnotations程序集 [英] Upgrading application for .Net Framework 4.5 - cannot get correct DataAnnotations assembly
问题描述
我已升级的应用程序的新构建失败。升级是为.Net Framework 4.0到4.5和EF到版本6.
错误消息是;
Models \ Mapping\vw_EmployeesAndJobTitlesMap.cs（47）：无法找到类型名称
'DatabaseGeneratedOption'。此类型已将
转发到程序集System.ComponentModel.DataAnnotations，
Version = 4.0.0.0，Culture = neutral，PublicKeyToken = 31bf3856ad364e35。

当我点击日志中的链接时，这行似乎是问题;
使用System.ComponentModel.DataAnnotations.Schema;
EF是版本6.

如何解决这个问题？
在.NET Framework 4.5中， EF注释从 EF.dll 移动到 System.ComponentModel.Annotations 程序集。
似乎即使您定位到.NET Framework 4.5，您仍然可以在某个地方引用 EntityFramework.dll v4.4.0.0 p>
因此，您的类将使用4.4.0.0程序集中的属性进行编译。
在运行时，较新的 EntityFramework.dll （5.0.0.0）正在使用，它从 System.ComponentModel.DataAnnotations 程序集中查找属性 - 那些不能因为你有 EF.dll 4.4.0.0，因此看起来像属性被忽略。
My new build for the application I have upgraded fails. The upgrade is for .Net Framework 4.0 to 4.5 and EF to version 6. The error message is;

In the log I get the following;

When I click on the link in the log, it is this line that seems to be the problem;
using System.ComponentModel.DataAnnotations.Schema;
EF is version 6.
The error messages says that c:\Windows\Microsoft.NET\assembly\GAC_MSIL\System.ComponentModel.DataAnnotations\v4.0_4.0.0.0__31bf3856ad364e35\System.ComponentModel.DataAnnotations.dll does not exist, but when I look it does exist.

How do I fix this?
In .NET Framework 4.5, EF annotations were moved from EF.dll to System.ComponentModel.Annotations assembly.
It seems that even though you target .NET Framework 4.5, you still have a reference to EntityFramework.dll v4.4.0.0 somewhere.
As a result your classes are compiled with attributes from the 4.4.0.0 assembly.
At runtime the newer EntityFramework.dll (5.0.0.0) is being used and it looks for attributes from System.ComponentModel.DataAnnotations assembly - Those cannot be found since you have the ones from EF.dll 4.4.0.0 and therefore it looks like attributes are being ignored.
这篇关于升级.NET Framework 4.5的应用程序 - 无法获取正确的DataAnnotations程序集的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
