我遇到了完全相同的问题。

原因 - 糟糕的IIS配置文件。

I had the exact same problem.
The reason - bad IIS config file.

尝试删除自动创建的 IISExpress 文件夹，该文件夹通常位于％userprofile％/ Documents ，例如 C：\ Users \ [you] \Documents\IISExpress 。

Try deleting the automatically-created IISExpress folder, which is usually located at %userprofile%/Documents, e.g. C:\Users\[you]\Documents\IISExpress.

别担心， VS应该再次创建 - 正确，这次 - 再次运行解决方案。

Don't worry, VS should create it again - correctly, this time - once you run your solution again.

编辑：删除命令行文件夹：

Command line for deleting the folder:

rmdir /s /q "%userprofile%\Documents\IISExpress"
