我在启动MVC应用程序时遇到以下异常，我甚至没有引用该程序集（是的，我知道我引用的其他程序集可以引用它。）
＆＃34;具有显示名称＆＃39; System.Web.Http＆＃39;未能加载＆＃34;
public class MvcApplication : HttpApplication
{
protected void Application_Start()
{
// I am getting the exception here:
AreaRegistration.RegisterAllAreas();
/...
}
}
例外的完整文本如下：
The assembly with display name 'System.Web.Http' failed to load in the 'Load'
binding context of the AppDomain with ID 2. The cause of the failure was:
System.IO.FileNotFoundException: Could not load file or assembly
'System.Web.Http, Version=5.0.0.0, Culture=neutral,
PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot
find the file specified.
在跳过此异常后，一切似乎都正常工作仍然不是一种舒服的感觉，不知道发生了什么。
要回答评论，这是我的nuget：
