MVC6 ne Pouvez pas trouver application.UseStaticFiles() lors du Démarrage

Je suis à jouer autour de la nouvelle ASPNET 5 bêta à l'aide de la dernière version de Code de Visual Studio (v0.3). Je ne veux pas mettre la VS2015 RC sur ma machine de travail. J'ai un barebones (Hello World) MVC6 app qui je l'ai pris en cours d'exécution après comprendre les bases de la dn* outils de ligne de commande.

Maintenant, je veux me servir d'un fichier statique. J'ai ajouté de Microsoft.AspNet.StaticFiles à mon projet.fichier json et restauré les paquets.

Mon projet.json:

{
    "version": "1.0.0-*",
    "webroot": "wwwroot",
    "exclude": [
        "wwwroot"
    ],
    "packExclude": [
        "**.kproj",
        "**.user",
        "**.vspscc"
    ],
    "dependencies": {
        "Kestrel": "1.0.0-*",
        "Microsoft.AspNet.Diagnostics": "1.0.0-*",
        "Microsoft.AspNet.Mvc": "6.0.0-*",
        "Microsoft.AspNet.Server.IIS": "1.0.0-*",
        "Microsoft.AspNet.Server.WebListener": "1.0.0-*",
        "Microsoft.AspNet.StaticFiles": "1.0.0-*"
    },
    "commands": {
        "web": "Microsoft.AspNet.Hosting --server Microsoft.AspNet.Server.WebListener --server.urls http://localhost:8080",
        "kestrel": "Microsoft.AspNet.Hosting --server Kestrel --server.urls http://localhost:8080"
    },
    "frameworks": {
         "dnx451": { },
         "dnxcore50": { }
    }
}

Mon Démarrage.cs:

using Microsoft.AspNet.Builder;
using Microsoft.Framework.DependencyInjection;

namespace EmailViewer
{
    public class Startup
    {
        public void ConfigureServices(IServiceCollection services)
        {
            services.AddMvc();
        }

        public void Configure(IApplicationBuilder app)
        {            
            app.UseErrorPage();
            app.UseStaticFiles(); 
            app.UseMvcWithDefaultRoute();
            app.UseWelcomePage(); 
        }
    }
}

Tout fonctionne bien jusqu'à ce que je comprennent app.UseStaticFiles() à quel point j'obtiens l'erreur suivante:

J'ai essayé d'utiliser ces versions:

• 1.0.0-beta4
• 1.0.0-beta6-12114

Je ne peux pas comprendre ce que je fais mal. Des idées? Merci à l'avance!
