EF7 Beta 4 : AddEntityFramework dont accept argument (Configuration)

I am going through this example: http://stephenwalther.com/archive/2015/01/17/asp-net-5-and-angularjs-part-4-using-entity-framework-7

and i am struggling with this code part:

using Microsoft.AspNet.Builder;
using Microsoft.Framework.DependencyInjection;
using Microsoft.Data.Entity;
using creaservo.com.Models;
using Microsoft.Framework.ConfigurationModel;
using Microsoft.AspNet.Hosting;

namespace creaservo.com
{
    public class Startup
    {
        public Startup(IHostingEnvironment env)
        {
            // Setup configuration sources.
            Configuration = new Configuration()
                .AddJsonFile("config.json")
                .AddEnvironmentVariables();
        }

        public IConfiguration Configuration { get; set; }


        public void ConfigureServices(IServiceCollection services)
        {
            services.AddMvc();

            // Register Entity Framework
            services.AddEntityFramework(Configuration)
                .AddSqlServer()
                .AddDbContext<MoviesAppContext>();
        }

        public void Configure(IApplicationBuilder app)
        {
            app.UseMvc();
        }
    }
}

The Problem is with 

        // Register Entity Framework
        services.AddEntityFramework(Configuration)
            .AddSqlServer()
            .AddDbContext<MoviesAppContext>();

where i get a build error:

Error   CS1501  No overload for method 'AddEntityFramework' takes 1 arguments

I saw in a lot of other examples the same use of a argument for Configuration.

No idea, what's wrong....

It looks like the tutorial you're following is using an older version of the EF7 framework. EntityFramework 7 beta 4 no longer accepts any parameters to AddEntityFramework. It looks like beta 5 is still on this same track, too.

I believe what you're looking for is this:

// Register Entity Framework
services.AddEntityFramework()
    .AddSqlServer()
    .AddDbContext<MoviesAppContext>(options =>
    {
        options.UseSqlServer(Configuration.Get("Data:DefaultConnection:ConnectionString"));
    });

This simplifies the structure that you need in the configuration file, because the MoviesAppContext only needs the connection string, not the EntityFramework and Data elements.
