I'm trying to launch an ASP.NET Framework in C# project on localhost but I'm getting this error from Visual Studio 2019.
Unable to launch the IIS Express Web server.
Output from IIS Express:
Failed to register URL "https://localhost:44318/" for site "***" application "/". Error description: Cannot create a file that already exists. (0x800700b7)
I'm sure that I don't have other servers running on localhost on the port 44318. When I'm using port 44317 or 8080 (is unused too) then, I've this problem in Google Chrome:
This site can’t provide a secure connection
Also answer below form this question Unable to launch the IIS Express Web server doesn't help me.
Try deleting the automatically-created IISExpress folder, which is usually located at
%userprofile%/Documents
, e.g.C:\Users\[you]\Documents\IISExpress
.
How could I solve this problem?
