This resolved the issue on Windows 10 after the last update

go Control Panel ->> Programs ->> Programs and Features ->> Turn Windows features on or off ->> Internet Information Services

But based on previous response it doesn't work unless checking all these options as on pic below

I had the same issue i resolved it by repairing the iis server in programs and features.

GO TO

Controll panel > uninstall a program and then right click the installed iis express server (installed with Visual Studio) and then click repair.

this is how i solved this issue

If using IIS:

  • control panel
  • Programs
  • open or close windows features
  • tick internet information services
  • then restart your visual studio

If using IIS Express:

Open 'Add/Remove Programs' from the old control panel and run a repair on IIS Express Or you might go Control Panel ->> Programs ->> Programs and Features ->> Turn Windows features on or off ->> Internet Information Services and check the checkbox as shown in the picture below:

This occurred to me when I applied the 2017 Fall Creator Update. I was able to resolve by repairing IIS 10.0 Express (I do not have IIS installed on my box.)

Note: As a user pointed out in the comments,

Repair can be found in "Programs and Features" - the "classic" control panel.

If you are okay with using the built in Visual Studio Development server or you don't want to or cannot install IIS, you can change the web server the project uses by going into

  1. Project Properties (right click project in solution explorer and select properties)

  2. select Web tab

  3. select "Use Visual Studio Development Server".

I don't know how it happened to me, but somehow this option was changed to "Use Local IIS Web Server" for one of my projects.

For me, it was happening because I had switched over to "Run as Administrator". Just one instance of VS was running, but running it as admin threw this error. Switching back fixed me right up.
