OWIN Service resolution Using Autofac

Question

I have an WebApi application using OWIN and Autofac. Although controllers and parameters get resolved correctly, I would like to be able to use `OwinContext.Get` to resolve types registered with Autofac. Is that posible? Already set`app.UseAutofacMiddleware(container);` and `config.DependencyResolver = new AutofacWebApiDependencyResolver(container);` By example, I registered `builder.Register(c => new AppConfig());` and I'd like to resolve it using `owinContext.Get()`.

Accepted Answer

The `IOwinContext.Get` uses the `Environment` dictionary, resolving objects registered directly with Owin, it does not take into account Autofac container.

I managed to do it by accessing the Autofac OwinLifetimeScope in the Environment property and using the scope to resolve the service.

You can access the LifetimeScope using this code

```
var scope=OwinContext.Get<Autofac.Core.Lifetime.LifetimeScope>("autofac:OwinLifetimeScope"); 
```

and then

```
scope.GetService(type)
```

You should check for nulls and write it in a better way, as Extension method maybe.
