我正在尝试为现有的 MVC 项目添加结果。

在线上

@(Html.UpshotContext().DataSource<DataServiceController>(x => x.GetAllProducts()))

我得到了例外

Could not load file or assembly 'System.Web.Http.Common, Version=4.0.0.0,
Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. 
The system cannot find the file specified.

我已安装的 nuget 软件包列表是

谷歌没有给我任何例外。有任何想法吗？

根据关于此线程的讨论： Current SPA (beta) is not compatible with MVC 4 RC

ASP.NET 团队建议人们暂时坚持使用 MVC4 beta + SPA Nuget 包。另一种建议是获取冲突库的代码并自己构建它们，但这只是在团队前进时要求头痛和返工。

尝试从NuGet安装它：

PM> Install-Package System.Web.Http.Common
