structuremap OWIN middleware to handle the container per owin context

structuremap.owin

StructureMapOWINMiddleware in remplacement of the IHttpModule :

//basic draft
 public class StructureMapOWINMiddleware : OwinMiddleware
    {
        public StructureMapOWINMiddleware(OwinMiddleware next)
            : base(next)
        {

        }

        public async override Task Invoke(IOwinContext context)
        {
            IoC.DependencyScope.CreateNestedContainer(); // I moved de dependencyScope static in the IOC Class
            await Next.Invoke(context); // Process the request with all other OWIN Middleware
            HttpContextLifecycle.DisposeAndClearAll(); //clean all
            IoC.DependencyScope.DisposeNestedContainer();
        }
    }

and in the startup class, on the first line to be sure the IOC is configured before everthing else : 

 IContainer container = IoC.Initialize();
 app.Use(typeof(StructureMapOWINMiddleware));
 
 
 public IContainer CurrentNestedContainer
        {
            get
            {
                if (OwinContext == null) //OwinContext is passed in the ctor
                    return null;
                return OwinContext.Get<IContainer>(NestedContainerKey);
            }
            set
            {
                OwinContext.Set<IContainer>(NestedContainerKey, value);
            }
        }
