到目前为止，我已经做过了吗:-

Have I have done so far:-

1. 更新了所有Nuget软件包
2. 已删除的obj文件夹内容
3. 运行aspnet_compiler.exe -p C:\ source \ Application \ MyAPI -v any -errorstack.它确实给出了相同的错误，但是在我添加了WebMatrix.data之后就停止了.

推荐答案

我发现了问题.大摇大摆的另一个PreApplicationStartMethod引起了该问题. 在删除该行之后，一切开始起作用.

I found the issue. there was another PreApplicationStartMethod in swagger that was causing the issue. After I removed that line things started working.
