我的 PC 上安装了 VS 11 Beta、.net 4.5 和 MVC 4 beta。我刚刚下载了最新的 RC,现在当我尝试运行 Web 项目时收到此错误消息。我尝试重新安装 .net 4.5 并卸载并重新安装 VS 12 RC,但这并没有奏效。我在这里尝试了这个建议,但也没有用。

我使用fuslogvw
并发现该项目是System.Web.Http.dll
从这里引用的
C:\Windows\Microsoft.Net\assembly\GAC_MSIL\System.Web.Http\v4.0_4.0.0.0__31bf3856ad364e35
而不是我的项目。重命名这个文件使我的项目工作,但我显然不能在我的共享主机站点上这样做。
我已经手动引用了 dll
C:\Program Files (x86)\Microsoft ASP.NET\ASP.NET MVC 4\Assemblies
并将其设置为Copy to Local
. 它仍然从gac_msil
. 我该如何覆盖这个?
