WCF會話主機ASP.NET版本

Question

我建立這充分說明現有的應用程序的WCF服務，而這個應用程序需要訪問ASP.NET會話 - 看會話的能力是一個要求我無法迴避。

我建立WCF項目 - 並具有以下設置在App.config中：

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

我還包括一個接口和文件中的服務的實現。在實施前，我有：

// 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 
{ 

這是一個REST服務，讓我的接口開始，如：

// 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(); 

服務本身託管在另一個Web應用程序 - 在SearchService.svc文件其中有這樣的：

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

，我已將此添加到託管應用程序的web.config：

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

我相信我做了所有正確的步驟 - 然而，當我嘗試運行Web應用程序我得到這個錯誤：

"

Answer 1

你提到的App.config - 這聽起來像您服務一個WCF服務庫，你在IIS下託管。如果是這樣的話，你需要從App.config中的WCF配置部分複製到託管服務的IIS應用程序的Web.config。

庫不使用配置文件 - 他們所使用的調用應用程序的配置文件。
