Étant donné votre vue partielle CartSummary, il semblerait que vous soyez dans une boucle infinie d’appel de la vue partielle à partir de la vue partielle. 

     @Html.ActionLink("Cart (" + ViewData["CartCount"] + ")", "Index", "ShoppingCart", new { id = "cart-status" })

     //if this is in CartSummary, then it is calling itself over and 
     //over (or not at all, thus the error.)
     @Html.RenderAction("CartSummary", "ShoppingCart");

Veuillez vérifier votre vue partielle pour les erreurs… J'ai eu un problème similaire aujourd'hui et mon problème était que j'ai renommé une propriété du modèle et que, dans la vue, il n'a pas changé.

Peut-être que c'est aussi votre problème. Essaye le.

Remarque: Je l’affiche dans la section réponse car je n’ai pas assez de réputation pour commenter sous votre question.

veuillez supprimer la ligne @model int du fichier CartSummary.cshtml.Il fonctionne pour moi.

J'ai eu ce problème aujourd'hui et il s'est avéré que j'avais accidentellement eu deux vues partielles nommées la même chose et celle qui s'appelait de manière récursive, changeant le nom de l'autre partie partielle, ce qui a permis au processus de s'écouler à nouveau.

Mon application renvoyait la même exception si j'étais connecté en tant que certain utilisateur.

J'ai constaté que j'avais sur mon contrôleur un AuthorizeAttribute qui modifiait le résultat de l'action en résultat RedirectToRoute pour cet utilisateur, ce qui entraînait une exception System.Web.Mvc.HttpHandlerUtil + ServerExecuteHttpHandlerAsyncWrapper, car les redirections à partir d'actions enfants ne font pas beaucoup de choses.

J'ai résolu ce problème en ajoutant une vérification aux attributs de la méthode OnAuthorization pour les actions enfants renvoyant redirecttorouteresult et en réécrivant le résultat dans EmptyResult pour elles.

Si vous obtenez une telle erreur, cela signifie qu’il ya un problème quelque part dans la pile de traitement. Appuyez sur Continuer et l’erreur complète sera affichée sur la page Web.

Dans mon cas, j'ai reçu l'exception "System.Web.Mvc.HttpHandlerUtil + ServerExecuteHttpHandlerAsyncWrapper", cliqué dessus, puis affichée sur le site Web:

Server Error in '/' Application.

The partial view '_Chat' was not found or no view engine supports the searched locations. The following locations were searched:
~/Views/Home/_Chat.aspx
~/Views/Home/_Chat.ascx
~/Views/Shared/_Chat.aspx
~/Views/Shared/_Chat.ascx
~/Views/Home/_Chat.cshtml
~/Views/Home/_Chat.vbhtml
~/Views/Shared/_Chat.cshtml
~/Views/Shared/_Chat.vbhtml

Facile à trouver une fois arrivé à ce point ...

Dans mon cas, il me suffisait de vérifier tous les liens de la vue à laquelle j'essaie d'accéder. 

Assurez-vous que toutes les actions du contrôleur ont une vue et exécutez à nouveau votre application, tout ira bien à nouveau.
