asp.net - 更新到 Asp.Net MVC 4 RTM 后无法加载类型 HttpControllerConfigurationAttribute

Question

我最初正在使用 ASP.Net MVC 4 Beta 和 EF 4.3.1 开发单页应用程序。我更新了 MVC 4 和 EF 5 的所有 NuGet 包。现在，每当我调用 ApiController 或 DbDataController 时，都会出现以下异常:

无法从程序集“System.Web.Http，Version=4.0.0.0，Culture=neutral，PublicKeyToken=31bf3856ad364e35”加载类型“System.Web.Http.Controllers.HttpControllerConfigurationAttribute”。

根据 MVC 4 发行说明，HttpControllerConfigurationAttribute 已被删除，但这并不是说我明确地使用了它。

Per controller configuration: ASP.NET Web API controllers can be attributed with a custom attribute that implements IControllerConfiguration to setup their own formatters, action selector and parameter binders. The HttpControllerConfigurationAttribute has been removed. MVC 4 Release Notes

我的问题是此时可能尝试加载此类型的是什么？

编辑:我现在认为这是因为自 MVC 4 Beta 以来 SPA 位尚未更新，并且其中存在 Controller 配置属性。

每个 Controller 配置:ASP.NET Web API Controller 可以使用实现 IControllerConfiguration 的自定义属性来设置自己的格式化程序、操作选择器和参数绑定(bind)器。 HttpControllerConfigurationAttribute 已被删除。 MVC 4 发行说明
