Middleware injection doesn't work with ACTNARS about autofac.owin HOT 5 CLOSED

Do you have a simple example that reproduces this issue? It sounds like a weird one and there isn't much to go on here.

I'll work to get an example out this weekend.

from autofac.owin.

I was able to replicate the issue in this project:
WebApplication1.zip

I'm not sure what the root cause is yet, but it's reproduced.

from autofac.owin.

The problem appears to be in the AutofacAppBuilderExtensions class in UseAllMiddlewareRegisteredInContainer. Specifically, we get the list of middleware like this:

var services = container.ComponentRegistry.Registrations.SelectMany(r => r.Services)
    .OfType<TypedService>()
    .Where(s => s.ServiceType.IsAssignableTo<OwinMiddleware>() && !s.ServiceType.IsAbstract)
    .Select(service => typeof(AutofacMiddleware<>).MakeGenericType(service.ServiceType))
    .Where(serviceType => !container.IsRegistered(serviceType));

With ACTNARS registered, that last bit .Where(serviceType => !container.IsRegistered(serviceType)) fails because it thinks everything is registered. I'm guessing the real intention of this filter was to get rid of any accidental inclusion of AutofacMiddleware<T> itself.

Let me see if I can fix that up.

As soon as the build completes I'll be pushing a new version. This will probably be the 4.0.0 release/stable version.
