messages via SOAP plaids CommunicationException

Question

Voici comment mon service est mis en place:

myServiceHost = new ServiceHost(typeof(ChatCommunicationService), new Uri("http://localhost:8080")); 
myServiceHost.AddServiceEndpoint(typeof(IChatService), new WSHttpBinding(), "Soap"); 
myServiceHost.Open(); 

Voici comment mon client webservice est mis en place:

ChannelFactory<IChatService> scf = new ChannelFactory<IChatService>(new WSHttpBinding(), "http://localhost:8080/Soap"); 
_chatService = scf.CreateChannel(); 

Mais quand je l'utilise dans mon application Je reçois un System.ServiceModel.CommunicationException. J'ai essayé pendant longtemps et je sais comment le résoudre. Googling cela montre quelque chose à propos de la définition de keepalive à false mais je ne sais pas où le définir.

Note: Cela fonctionne au début (je peux envoyer un message via SOAP) mais il émet toujours une exception au même endroit. Parler directement à ma base de données, je n'obtiens aucune exception. Je dois utiliser SOAP.

Je vous serais reconnaissant si quelqu'un pouvait aider :)

de l'exception, il ressemble à votre service ferme la connexion sous-jacente au cours du traitement. Pouvez-vous vérifier que votre service est toujours en cours d'exécution au moment où la demande a lieu dans le client. Au pire, ajoutez des messages Console.WriteLine qui enregistrent le début et la fin du service.
