Session WCF Hébergement ASP.NET Problème

Question

Je construis un service WCF qui parle à une application existante, et cette application nécessite l'accès aux sessions ASP.NET - la possibilité de voir des sessions est une exigence que je ne peux pas contourner.

I construit le projet WCF - et ont le paramètre suivant dans App.config:

<system.serviceModel> 
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" /> 

J'ai aussi inclus une interface et une implémentation du service dans le fichier. Devant la mise en œuvre, j'ai:

// NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "Service1" in both code and config file together. 
[AspNetCompatibilityRequirements(RequirementsMode = 
    AspNetCompatibilityRequirementsMode.Required)] 
public class SearchService : ISearchServiceInterface 
{ 

Ceci est un service REST, donc mon interface commence comme:

// NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IService1" in both code and config file together. 
[ServiceContract] 
public interface ISearchServiceInterface 
{ 

    [OperationContract] 
    [WebInvoke(BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Json)] 
    string LoginToWebService_POST(Altec.Framework.Authorization auth); 

    [OperationContract] 
    [WebInvoke(BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Json)] 
    string GetTopLevelFolderName_POST(); 

Le service lui-même est hébergé dans une autre application Web - dans un fichier SearchService.svc qui a ceci:

<%@ServiceHost language=c# Debug="true" Service="Altec.UI.Web.SearchService.SearchService" %> 

et j'ajouté à la web.config de l'application d'hébergement:

<system.serviceModel> 
     <serviceHostingEnvironment aspNetCompatibilityEnabled="true"/> 

je crois que je l'ai fait toutes les bonnes mesures - et pourtant lorsque je tente de lancer l'application web je reçois cette erreur:

"

Vous avez mentionné App.config - il semble que votre service est une bibliothèque de services WCF que vous hébergez sous IIS. Si c'est le cas, vous devez copier la section de configuration WCF depuis le fichier App.config vers le fichier Web.config de l'application IIS hébergeant votre service.

Les bibliothèques n'utilisent pas les fichiers de configuration - elles utilisent le fichier de configuration de l'application appelante.
