ASP.net Identity, IoC and sharing DbContext

Question

Have anyone been successful in attaching an IoC with OWIN ASP.NET Identity to share the same DbContext as the WebApi (or MVC) application?

I would like that if ASP.Net i

EDIT: added instantiating the OWIN pipeline as per comment.

As the IdentityDbContext used by ASP.NET Identity inherits from DbContext, you can simply create your own implementation inheriting from IdentityDbContext like so

public class ApplicationContext : IdentityDbContext<ApplicationUser>
{
     //additional DbSets
    public DbSet<OtherEntity> OtherEntities { get; set; } 
}

public class ApplicationUser : IdentityUser
{
    //any custom properties you want for your user.
}

public class OtherEntity
{
    [Key]
    public int Id { get; set; }
}

now as far as using IoC, from a unity perspective, I register an instance of the UserStore like so

public static void RegisterTypes(IUnityContainer container)
{
    container.RegisterType<IUserStore<ApplicationUser>, UserStore<ApplicationUser>>(new InjectionConstructor(typeof(ApplicationContext)));
}

then create a wrapper around the user manager

public class ApplicationUserManager : UserManager<ApplicationUser>
{
    public ApplicationUserManager(IUserStore<ApplicationUser> store) : base(store)
    {
    }
}

and inject that wherever I need a user manager.

As for the OWIN pipeline, you need to instantiate the OAuthAuthorizationProvider through your container, like so.

container.RegisterType<IOAuthAuthorizationServerProvider, ApplicationOAuthProvider>(new InjectionConstructor("self", typeof(ApplicationUserManager)));

then for example in WebApi, you need to simply get the instance from the container in startup.

static Startup()
        {
            OAuthOptions = new OAuthAuthorizationServerOptions
            {
                TokenEndpointPath = new PathString("/Token"),
                Provider = (IOAuthAuthorizationServerProvider)GlobalConfiguration.Configuration.DependencyResolver.GetService(typeof(IOAuthAuthorizationServerProvider)),
                AccessTokenExpireTimeSpan = TimeSpan.FromDays(5),
                AllowInsecureHttp = true,
                RefreshTokenProvider = new SimpleRefreshTokenProvider()
            };
        }
