如果我删除 WebActivatorEx 包，一切都会再次运行，但我需要 WebActivatorEx 才能使用 DI。

我在网上找不到任何东西来暗示问题可能是什么。我尝试Startup在命名空间中创建一个类，该类Pharma.Mvc调用了一个静态方法Configuration，但似乎无法解决问题。

此外，在我安装包之前，没有Pharma.Mvc命名空间，也没有Startup类。所以我真的很困惑为什么会这样。

当我构建应用程序时，我的目标是 ASP.NET 4.5.1 框架，但是我注意到它在底部的堆栈跟踪中读取Microsoft .NET 4 Framework Version:4.0.30319，我不确定这是否正确。

我正在使用带有 WebApi 的 OWIN 中间件，因此需要一个具有以下程序集属性的 Startup 类 [程序集：OwinStartup(typeof(Startup))]

我还为 WebApi 使用了 Swagger 接口，并通过 nuget 包安装了它。安装添加了具有以下程序集属性的 SwaggerConfig 类 [程序集：PreApplicationStartMethod(typeof(SwaggerConfig), "Register")]

启动 WebApi 时，程序集属性导致此异常。我从 SwaggerConfig 类中删除了程序集属性，一切正常。

原来是 bin 文件夹中的旧程序集，不再引用，导致问题。
