我有一个带有Angular的.NET Core项目，一切都正常。我在4周内没有触及JS端，而是专注于.NET方面的工作。这也涉及到更新一些npm包等。
现在我发现main.js没有改变，原因是ts-js链接似乎消失了。例如，对ts文件进行更改（甚至创建新文件）不会生成相应的js文件。
Webpack命令运行正常。在VS 2017中构建也没问题。
我的tsconfig.json如下：
我的webpack.config.js文件
我的webpack.config.vendor.js文件

似乎没有人真正知道这些东西是如何工作的，因为通常有100种关于问题的理论，但很少有解决方案，但希望能够解决。
