Unable to load application or execute command 'Microsoft.AspNet.Server.Kestrel'

I am trying to deploy my ASP.NET 5 WebApi to a remote server (Windows server 2008 R2) and am having trouble getting it to run correctly with IIS.

project.json

{
  "webroot": "wwwroot",
  "version": "1.0.0-*",

  "dependencies": {
    "App.Data": "1.0.0-*",
    "App.Model": "1.0.0-*",
    "App.Repository": "1.0.0-*",
    "App.ViewModel": "1.0.0-*",
    "AutoMapper": "4.1.1",
    "Microsoft.AspNet.Authentication": "1.0.0-rc2-16009",
    "Microsoft.AspNet.Authentication.JwtBearer": "1.0.0-rc2-16009",
    "Microsoft.AspNet.Diagnostics": "1.0.0-rc2-16136",
    "Microsoft.AspNet.IISPlatformHandler": "1.0.0-rc2-15873",
    "Microsoft.AspNet.Mvc": "6.0.0-rc2-16377",
    "Microsoft.AspNet.Server.Kestrel": "1.0.0-rc2-16017",
    "Microsoft.AspNet.Server.WebListener": "1.0.0-rc2-15932",
    "Microsoft.AspNet.StaticFiles": "1.0.0-rc2-15916",
    "Microsoft.Framework.Configuration.Json": "1.0.0-rc1-15666",
    "Microsoft.Framework.Logging": "1.0.0-rc1-15644",
    "Microsoft.Framework.Logging.Console": "1.0.0-rc1-15644",
    "Microsoft.IdentityModel.Protocols.OpenIdConnect": "2.0.0-rc1-211120828"
  },

  "commands": {
    "kestrel": "Microsoft.AspNet.Server.Kestrel",
    "web": "Microsoft.AspNet.Server.Kestrel"
  },

  "frameworks": {
    "dnx451": { }
  },

  "exclude": [
    "wwwroot",
    "node_modules"
  ],
  "publishExclude": [
    "**.user",
    "**.vspscc"
  ]
}

when I try to access to the application from the browser, I get no response. And when I execute web.cmd on the server, I get the following error:

Error: Unable to load application or execute command 'Microsoft.AspNet.Server.Ke
strel'. Available commands: kestrel, web.

Thank you for your help

Make sure you have all the dependencies installed on target server. Run dnu list in cmd to see all the project dependencies.

If some of them are not installed (they will appear red) run dnu restore to restore all packages.

You can also make sure that your project builds successfully by running dnu build

Hope it helps..
