asp.net - WebActivatorEx.ActivationManager 类型错误引发异常...参数计数不匹配

Question

安装 Microsoft.Owin.* 后，我收到此错误。目标.Net框架:4.5.2。网络激活器:2.2.0我在另一个项目中有相同的设置，看起来效果很好。请帮我调试或修复这个问题。

到目前为止我已经完成了吗:-

1. 更新了所有 Nuget 软件包
2. 已删除 obj 文件夹内容
3. 运行 aspnet_compiler.exe -p C:\source\Application\MyAPI -v everything -errorstack 。它确实给出了同样的错误，但在我添加 WebMatrix.data 后停止了。

完整错误详细信息:-

我发现了这个问题。 swagger 中的另一个 PreApplicationStartMethod 导致了该问题。删除该行后，一切开始工作。
