今天因為早晨刪注冊表文件，VS 2019不能用了，重裝了一遍但時間有點長，就下了個 Rider ,但是Debug的時候報了下面的錯
An error occurred while reading configuration information.
Make sure that the configuration file xxxxxxxxx\.idea\config\applicationhost.config exists,
it is accessible, and contains valid configuration information.
然后解決辦法是
右擊項目 -> 屬性 -> 'Web' 然后改成IIS Express
