安装 Microsoft.Owin.* 后出现此错误。目标 .Net 框架：4.5.2。Web Activator: 2.2.0 我在另一个项目中有相同的设置，而且似乎工作正常。请帮我调试或解决这个问题。

到目前为止我做过吗：-

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

完整的错误详细信息：-

参数计数不匹配。说明：执行当前 Web 请求期间发生未处理的异常。请查看堆栈跟踪以获取有关错误及其源自代码的位置的更多信息。

我发现了这个问题。招摇中还有另一个 PreApplicationStartMethod 导致了这个问题。在我删除那条线之后，事情开始起作用了。
