IServiceProvider in ASP.NET Core

Question

I starting to learn changes in ASP.NET 5(vNext) and cannot find how to get IServiceProvider, for example in \"Model\"\'s method

public class Entity 
{
     publ

Instead of getting your service inline, try injecting it into the constructor.

public class Startup
{
    public void ConfigureServices(IServiceCollection services)
    {
        services.AddTransient(typeof(DataContext));
    }
}

public class Entity
{
    private DataContext _context;

    public Entity(DataContext context)
    {
        _context = context;
    }

    public void DoSomething()
    {
        // use _context here
    }
}

I also suggest reading up on what AddTransient means, as it will have a significant impact on how your application shares instances of DbContext. This is a pattern called Dependency Injection. It takes a while to get used to, but you will never want to go back once you do.
