asp.net - 需要帮助解决.NET webapi2应用程序启动

我有一个有效的webapi2应用程序，它引用了我们拥有的一些常见/共享库程序集。这些共享库具有不同的存储库，并且它们在构建过程中作为nuget包发布。最近，我将webapi2应用程序的nuget包引用更新为这些常见包的更新版本。其中一个程序集的较新版本Microsoft.Icm.Common.Web不再具有属性WebApiExceptionHandlerAttribute。因此，在构建webapi2应用程序时，我在webapi2控制器类中删除了对该属性的所有引用。当我重新构建应用程序并将其部署到我们的一个临时环境时，我看到以下类型加载异常：

消息：无法加载类型＆＃39; Microsoft.Icm.Common.Web.WebApiExceptionHandlerAttribute＆＃39;来自assembly＆＃39; Microsoft.Icm.Common.Web，Version = 2.4.0.0，Culture = neutral，PublicKeyToken = null＆＃39;。

即使我最近构建的webapi2应用程序不再引用不可用的WebApiExceptionHandlerAttribute（在较新的Microsoft.Icm.Common.Web程序集中），但在运行应用程序时，看起来似乎正在使用不可用的属性。我使用了像Resharper的dotnetpeek这样的工具并搜索了术语＆＃34; WebApiExceptionHandlerAttribute＆＃34;在binplaced程序集中，我没有看到该属性的任何匹配项。那么，我如何弄清楚为什么Web应用程序仍然试图在应用程序启动时找到该类型？
