Unable to Launch IIS Express

Unable to Launch IIS Express

This error usually occurs when moving a project from one computer to another. The IIS Express engine that is built into Visual Studio has an issue starting if the solution was moved from a different computer. Fortunately, the solution is rather simple.

  • Quit Visual Studio
  • In the Solution Folder delete the .vs folder
    • You will need to turn on show hidden files and folder to see the .vs folder
  • Start Visual Studio and open the solution again
  • Run the application
    • At this point the site should launch in the web browser
