Missing components to configure and manage IIS express

Question

I am attempting to launch & debug an ASP.NET 5 project from within Visual Studio, and getting the error message "Missing components to configure and manage IIS express".

The solution builds without error. But IIS Express will not start and allow me to debug.

I have tried restarting Visual Studio and ensuring that the ports used by the project are free to use.

According to the error message, we can have a try with the following:

1.Close solution, delete .vs folder if this issue only happens in the specific solution

2.Delete the folder IIS express folder: C:\Users\UserName\Documents\iisexpress

3.Delete temporary ASP.NET Files located: C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\root
