类型或名称空间名称"Caching"在名称空间"System.Runtime"中不存在 [英] The type or namespace name 'Caching' does not exist in the namespace 'System.Runtime'

问题描述

我知道通常对此有一个简单的解决方案，即在添加引用中引用dll.但是我已经添加了参考，并且system.runtime.caching出现在我的参考列表中，但错误仍然显示.

I know there is usually a simple solution to this which is reference the dll in add references. But I have added the reference and system.runtime.caching appears in my references list but the error still displays.

该错误在运行时显示在浏览器中，因此可以编译.

The error displays in the browser in runtime so it does compile.

我已删除并重新添加了引用，但仍然没有运气.我已经重新启动VS 2012并重新启动.

I have removed and re added the reference but still no luck. I have restarted VS 2012 and restarted.

Visual Studio 2012.net Framework 4.5

推荐答案

我遇到了同样的问题，并且发现必须手动添加:

I had the same issue, and I found out that I manually had to add:

<assemblies>
  <add assembly="System.Runtime.Caching, Version=4.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A"/>
</assemblies>

到我的 web.config 文件.
