How to get OwinContext from Global.asax?

Question

I am trying to set up my Dependency Injection and I am in the need of injecting a IAuthenticationManager from ASP.NET Identity to an OwinContext.

For this I am from my Global.asax -> ServiceConfig.Configure() running:

 container.Register(() => HttpContext.Current.GetOwinContext().Authentication);

But when I am running my application I get this message:

No owin.Environment item was found in the context

Why is this HttpContext.Current.GetOwinContext() not available from Global.asax?

Startup.cs

[assembly: OwinStartupAttribute(typeof(MyApp.Web.Startup))]
namespace Speedop.Web
{
    public partial class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            ConfigureAuth(app);
        }
    }
}

Startup.Auth.cs

public partial class Startup
{
    public void ConfigureAuth(IAppBuilder app)
    {
        app.UseCookieAuthentication(new CookieAuthenticationOptions
        {
            AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
            LoginPath = new PathString("/Account/Login"),
            Provider = new CookieAuthenticationProvider
            {
                OnValidateIdentity = SecurityStampValidator.OnValidateIdentity<UserManager<User, int>, User, int>(
                    validateInterval: TimeSpan.FromMinutes(30),
                    regenerateIdentityCallback: (manager, user) => manager.CreateIdentityAsync(user, DefaultAuthenticationTypes.ApplicationCookie),
                    getUserIdCallback: (id) => (Int32.Parse(id.GetUserId()))
                    )
            }
        });

        app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);
    }
}

look at [this answer](http://stackoverflow.com/questions/20168978/do-i-need-a-global-asax-cs-file-at-all-if-im-using-an-owin-startup-cs-class-and). Mainly, Global.asax is called before Startup.cs — Jonesopolis, Jul 09 '14 at 17:46
Hm, I do have 'Microsoft.Owin.Host.SystemWeb.dll' in my directory. I tried moving everything to Startup.cs from my Global.asax after I did ConfigureAuth(...) still the same message comes. — janhartmann, Jul 09 '14 at 18:05
I just tried creating a whole new sample app and tried getting the OwinContext with the same results. There must be a way :-) — janhartmann, Jul 09 '14 at 18:36
[Here's a discussion](https://simpleinjector.codeplex.com/discussions/539965) about Owin with Simple Injector. Perhaps that helps. — Steven, Jul 11 '14 at 06:25
Thanks @Steven, I will try when I get home and let you know. :-) — janhartmann, Jul 11 '14 at 07:22
Unfortunately it did not work, maybe I should find another solution on how to inject a IAuthenticationManager into my service. — janhartmann, Jul 12 '14 at 06:50

I fixed this with the following:

container.RegisterPerWebRequest(() =>
{
    if (HttpContext.Current != null && HttpContext.Current.Items["owin.Environment"] == null && container.IsVerifying())
    {
        return new OwinContext().Authentication;
    }
    return HttpContext.Current.GetOwinContext().Authentication;

});

Seems like the OwnContext is not present at startup, so I'll wait for it and inject it once its present. Please note that the container.IsVerifying() is present in SimpleInjector.Advanced

What is this "RegisterPerWebRequest()" ? where do you get it from ? Unity doesn't seem to have such a method or extention – Marty Dec 31 '14 at 13:34
Found it. You're using SimpleInjector. ok. Question is how do You register the type. For example, controller needs a repo, that need the IauthManager. – Marty Dec 31 '14 at 14:24
Does anyone know how to do this with Castle Windsor? – mayabelle Mar 10 '15 at 19:05

In Castle windsor you can do the following: container.Register(Component.For().UsingFactoryMethod( () => { if (HttpContext.Current != null && HttpContext.Current.Items["owin.Environment"] == null) { return new OwinContext().Authentication; } return HttpContext.Current.GetOwinContext().Authentication; }).LifestylePerWebRequest()); – Ron Sijm Mar 16 '15 at 14:57
