EF7: DBContext configuration on ASP.NET 5 Web-API

Question

I'm currently developing an ASP.NET 5 Web-API application with VS2015 Ultimate Preview. Some things have changed about configuring EF7 on this new platform.

I've already checked the help in this page: https://github.com/aspnet/EntityFramework/wiki but it doesn't show all the step needed to successfully complete a connection with EF7 (it shows only a partial answer)

Can anyone bring a step-by-step tutorial on how would be the correct way to connect to a database (SQL Server) using EF7?. (not using old syntax like in MusicStore sample app but using more recent syntax)

Creating a new ASP.NET 5 Starter Web project shows a good starting point. Look at Startup.cs and config.json. — bricelam

Define more recent syntax please. The MusicStore app has a master branch which is for beta3 development currently and a dev branch which should be using the latest (beta4ish) code. — Nick-ACNB

basically what he is saying is that the musicStore app needs to be turned into a wiki so that people like netcito and myself can understand wtf is going on. Im currently wrestling with dnvm and dnx utility. Drips and drabs about that stuff too — PazoozaTest Pazman

The code should be the same as you linked in the sample app. You register the context in Startup.cs, within ConfigureServices method using the following code:

public void ConfigureServices(IServiceCollection services)
{
    // Add EF services to the services container.
    services
        .AddEntityFramework(Configuration)
        .AddSqlServer()
        .AddDbContext<MyDbContext>(options =>
         {
             options.UseSqlServer(Configuration.Get("Data:DefaultConnection:ConnectionString"));
         });
}

Then your MyDbContext will be available for dependency injection, and in your controllers you can do

public MyController(MyDbContext context)
{
   ...
}

That's it

that seems like there is a lot of "magic" behind those extension methods. Any documentation regarding what do they do exactly?
