I am attempting to setup a new work space and transfer all of my projects from my old computer to the new one. However, I am getting this error when I try to run IIS Expres
VS2017 and solution has .NET Core 1.1 web applications.
This did not help: Deleting .VS folder, removing all bin directories, restarting VS.
This helped: Installed latest SDK (.NET Core SDK 1.0.4) this issue got resolved.
I got this issue all of a sudden after a machine reboot followed by installing PHP for IIS, IIS URL Rewrite. But just try reinstalling the SDK – it might work fine with that itself, instead of going for the latest SDK.
