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:
