我添加了4.0版作为参考，所以我不确定为什么会收到该错误。我没有5.2，但看起来我需要5.2 ..但是，我无法在当前的开发环境中安装NuGet包，所以我不确定如何下载该DLL并在没有NuGet的情况下添加它。 / p>

Answer 1

如果项目在VS2013中启动，则默认模板引用MVC5，因此即使您向4.0二进制文件添加程序集引用，您的web.config仍然引用5.x（x代表当前的当前任何内容）项目已创建）。

您可以在此处下载MVC包：https://www.nuget.org/packages/Microsoft.AspNet.Mvc/然后解压缩.nupkg存档（使用7zip或类似文件）以获取.dll文件。

如果您不使用NuGet的原因是因为您使用的是没有NuGet支持的旧版Express，请升级到Community Edition。假设您拥有最新的WPI（Web平台安装程序），它在“工具”部分下列出，或者您可以从https://www.visualstudio.com/en-us/news/vs2013-community-vs.aspx下载。
