Visual Studio (2010 & 11) 继续引用 .net 4 程序集，即使在安装了 .net 4.5 之后 [英] Visual Studio (2010 & 11) keep referencing the .net 4 assemblies, even after .net 4.5 is installed

问题描述

.Net 4.5安装到目录

.Net 4.5 installs to the directory

C:\Windows\Microsoft.NET\Framework\v4.0.30319

C:\Windows\Microsoft.NET\Framework\v4.0.30319

Visual Studio 2010 安装 .Net 4.0 到目录

Visual Studio 2010 installs .Net 4.0 to the directory

C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.0

C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.0

即使在 VS 2010 之前安装了 .Net 4.5.现在，无论我做什么，VS 2010 和 VS 11 都会继续引用

Even if .Net 4.5 is installed prior to VS 2010. Now, no matter what I do, both VS 2010 and VS 11 keep referencing the assemblies in

C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.0

C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.0

即使我从项目中删除程序集，并通过浏览到 4.5 目录添加程序集

Even if I remove the assembly from the project, and add the assembly by browsing to the 4.5 directory

C:\Windows\Microsoft.NET\Framework\v4.0.30319

C:\Windows\Microsoft.NET\Framework\v4.0.30319

如何让 Visual Studio 引用位于此处的 .Net 程序集

How do I get Visual Studio to reference the .Net assemblies located here

C:\Windows\Microsoft.NET\Framework\v4.0.30319 ??

C:\Windows\Microsoft.NET\Framework\v4.0.30319 ??

谢谢
