问题描述
我在Framework 4.5.1上有一个网站。
编译时，缺少System.Data.DataExtensions的程序集引用错误。
I have a web site on Framework 4.5.1.When I compile I have a missing assembly reference error for System.Data.DataExtensions.
所以我要添加引用，在对话框关闭的框内打钩，重新编译。相同的程序集再次丢失。返回参考，程序集不再被打勾。它确实将其添加到web.config中，但引用始终消失。
So I go to add a reference tick the box close the dialog , recompile. Same assembly is missing again. Go back to references and the assembly is no longer ticked. It does add it the the web.config but the reference always disappears.
我遇到了此链接
但是解决方案仅使用System.Data而不是System.Data.DataExtensions。但是我的using语句已经仅仅是System.Data。
I came across this link similar issuebut the solution was only having using System.Data instead of using System.Data.DataExtensions. But my using statement are already only System.Data.
任何人都可以提供帮助吗？
Can anyone assist ?
推荐答案
好，看来当项目迁移到4.5.1框架时，Web配置文件并未更新，并且仍然包含对3.0框架的引用。
这就是阻止添加程序集引用的原因。
Ok it seems that when the project was migrated to 4.5.1 framework the web config file wasn't update and still contains a reference to the 3.0 framework.That is what was is preventing the assembly reference being added.
升级框架似乎不会使用所做的更改来更新Web配置。
Upgrading the framework seems not to update the web config with the changes.
