我使用fuslogvw,发现该项目从这里引用了System.Web.Http.dll

C:\Windows\Microsoft.Net\assembly\GAC_MSIL\System.Web.Http\v4.0_4.0.0.0__31bf3856ad364e35

而不是我的项目.重命名此文件使我的项目工作,但我显然不能在我的共享托管网站上这样做.

我已经手动引用了dll

C:\Program Files (x86)\Microsoft ASP.NET\ASP.NET MVC 4\Assemblies

并将其设置为复制到本地.仍然从gac_msil加载.如何覆盖这个？

解决方法

我有同样的问题,并发现这个问题,而谷歌在错误.
当我看到我的窗口上安装的程序,我看到有3个MVC 4’应用程序安装：

> MVC 4 VS 2010工具
> MVC 4
> MVC 4(Bundle)

我卸载了“MVC 4”应用程序,然后我的项目工作正常.
