Unable to launch the IIS Express Web server (various cases in answers)
Re: Unable to launch the IIS Express Web server (various cases in answers)
I had the exact same problem.
The reason - bad IIS config file.
Try deleting the automatically-created `IISExpress` folder, which is usually located at `%userprofile%/Documents`, e.g. `C:\Users\[you]\Documents\IISExpress`.
Don't worry, VS should create it again - correctly, this time - once you run your solution again.
EDIT: Command line for deleting the folder:
```
rmdir /s /q "%userprofile%\Documents\IISExpress"
```
