'Microsoft.AspNet.Server.Kestrel' issue while hosting in IIS

I have an ASP.NET Core MVC 6 Web API project which, when hosted on IIS, gives the below error:

Error: Unable to load application or execute command     'Microsoft.AspNet.Server.Kestrel'. Available commands: web, ef.
System.IO.FileNotFoundException: The system cannot find the file     specified.     (Exception from HRESULT: 0x80070002)

Contents of project.json:

  "exclude": [
    "wwwroot",
    "node_modules"
  ],

}

Please note, I have tried deleting the global.json file, and also tried running the commands dnu list, dnu restore, dnu build. Still getting the same error.
