我有一个“MVC 4”项目,我想将一个程序集添加到web.config文件,但我不知道我应该把它放在哪里。我尝试任何方式,但我找不到解决方案。
每次我收到此错误:
您必须添加对程序集'System.Data.Entity的引用, Version = 4.0.0.0,Culture = neutral,PublicKeyToken = b77a5c561934e089'。
这是我的web.config文件:
<?xml version="1.0" encoding="utf-8"?>

请帮帮我。
感谢。

这很简单。查看web.config中的编译部分:
<compilation debug="true" targetFramework="4.0"/>
现在打开这个部分并将你的程序集放在里面:
<compilation debug="true" targetFramework="4.0">
<assemblies>
<add assembly="System.Data.Entity, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
</assemblies>
</compilation>
本节中的库在编译时检查,它与运行时绑定无关。

我刚刚在VS Express 2012 for Web中遇到了与MVC 4相同的问题,但是,虽然Alfonso的答案比我在网上找到的任何其他内容更有帮助,但遗憾的是它没有清除我项目中的错误。在互联网上做了一些研究(无济于事),然后只是在Visual Studio上,我发现了以下解决方案。
除了将EntityFramework添加到我的项目的引用并将标记添加到我的Web.config之外,我还必须采取以下步骤来满足编译器:
