I'm developing a web application using Visual Studio 2019. Things will be working fine; then out of nowhere I get the following error:
Unable to connect to the configured development Web server.
Output from IIS Express:
Failed to register URL "http://localhost:2366/" for site "NSM" application "/". Error description: The process cannot access the file because it is being used by another process.
(0x80070020)
What is hanging? How do I fix this???
