WebActivatorEx在应用程序启动时导致ArgumentException
在安装了ArgumentException nuget包之后，当我试图访问一个页面时，我一直得到下面的WebActivatorEx。
Server Error in '/PharmaDotnet/ux' Application.
The type Pharma.Mvc.Startup doesn't have a static method named Configuration

Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.34249 如果我删除了WebActivatorEx包，一切都会再次正常工作，但我需要使用WebActivatorEx才能使用DI。
我在网上找不到任何关于这个问题的建议。我尝试使用一个名为Startup的静态方法在Pharma.Mvc命名空间中创建一个Configuration类，这个方法似乎没有解决这个问题。
而且，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发生这种事。
在构建应用程序时，我的目标是ASP.NET 4.5.1框架，但是我注意到，在底部的堆栈跟踪中，它读取Microsoft .NET 4 Framework Version:4.0.30319，我不确定这是否正确。

它原来是bin文件夹中的一个旧程序集，该程序集不再被引用，从而导致问题。

我使用带有WebApi的OWIN中间件，因此需要一个具有以下程序集属性程序集的启动类: OwinStartup(typeof( Startup ))
我还为WebApi使用Swagger接口，并通过nuget包安装它。安装添加了具有以下程序集属性程序集的PreApplicationStartMethod(typeof(SwaggerConfig)，类: SwaggerConfig“寄存器”)
程序集属性在启动WebApi时导致此异常。我从SwaggerConfig类中删除了程序集属性，一切都正常。
