SignalR provoquant de graves questions sur la mise à niveau

Après deux jours, j'ai été en mesure d'obtenir enfin la nouvelle SignalR installé;cependant, je suis confronté à un autre problème.

J'ai retiré le spécifique Owin Assemblée ou perdu de référence, certains comment.

J'ai vérifié mon bac, de paquets, de référence et des dossiers et de l'original de tous les Owin les conventions de nommage sont visibles.

Quelqu'un me sauver de cette tragédie et de me montrer comment résoudre ce problème?

Ici est le serveur d'erreur renvoyé à partir de iis.

Étiez-vous à l'aide de nuget pour gérer cela?
Juste un conseil: Si ce message d'erreur avec un jouet exemple, assurez-vous que votre index.html (ou autre) de la page est marquée comme la page de démarrage de Visual Studio.
