服务器错误/应用程序出现以下错误消息：更改为MVC5后无法加载文件或程序集'Microsoft.Web.Infrastructure

问题描述

最近，我们将MVC4更新为MVC5。启动Web服务时，我有一个用于报告目的的Web服务，出现以下错误

[FileNotFoundException: Could not load file or assembly 'Microsoft.Web.Infrastructure,Version=1.0.0.0,Culture=neutral,PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.]

我没有在我的服务中引用此 Microsoft.Web.Infrastructure.dll ，但是升级到MVC5后出现此dll问题。有帮助吗？

解决方法

Microsoft.Web.Infrastructure.dll 是密钥库。您应该添加此选项，这可能是内部需要/引用的一项。
您可以在 packages.config 文件和web.config
中检查所有dll引用。
或者它可能出现在本地，但是您没有将它在其属性中将本地复制到True
