Go to microsoft site "https://www.microsoft.com/net/download/dotnet-core/runtime-2.1.0-rc1" and install "Hosting Bundle Installer":

Before installing this you have to install the right version of runtime: https://www.microsoft.com/net/download/dotnet-core/runtime-2.1.0-rc1 Than install the right version of "Hosting Bundle Installer".

"Hosting Bundle Installer" is: .NET Core Windows Server Hosting bundle installs the .NET Core Runtime, .NET Core Library, and the ASP.NET Core Module. The module creates a reverse proxy between IIS and the Kestrel server on Windows platforms.

The identity under which your web application runs in IIS doesn't have full access to the folder in which the web.config file is found. Which version of IIS are you using? Assuming 7, you can view/change the identity through the 'Advanced Settings' of the application pool that hosts your application. Folder permissions can be granted via Windows Explorer in the usual way.
