WCF会话ASP.NET托管问题

我正在构建一个与现有应用程序对话的WCF服务，该应用程序需要访问ASP.NET会话-查看会话的能力是我无法回避的要求

我构建了WCF项目，并在App.config中设置了以下内容：

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

这是一个REST服务，因此我的界面启动如下：

// 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();

服务本身托管在另一个web应用程序中，位于SearchService.svc文件中，该文件具有以下内容：

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

我将其添加到托管应用程序的web.config中：

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

我相信我做了所有正确的步骤，但是当我尝试运行web应用程序时，我遇到了以下错误：

System.InvalidOperationException:此服务需要ASP.NET 兼容，并且必须托管在IIS中。在中托管服务 在web.config中打开ASP.NET兼容性的IIS，或设置 AspNetCompatibilityRequirementsAttribute.AspNetCompatibilityRequirementsMode 属性设置为非必需的值。在 System.ServiceModel.Activation.AspNetEnvironment.ValidateCompatibilityRequirementsAspNetCompatibilityRequirementsMode 相容性模型 System.ServiceModel.Activation.AspNetCompatibilityRequirementsAttribute.System.ServiceModel.Description.IServiceBehavior.ValidateServiceDescription 说明，ServiceHostBase ServiceHostBase位于 System.ServiceModel.Description.DispatcherBuilder.ValidatedDescriptionServiceDescription 说明，ServiceHostBase serviceHost位于 System.ServiceModel.Description.DispatcherBuilder.InitializeServiceHostServiceDescription 说明，ServiceHostBase serviceHost位于 System.ServiceModel.ServiceHostBase.InitializeRuntime位于 System.ServiceModel.ServiceHostBase.OnBeginOpen位于 System.ServiceModel.ServiceHostBase.OnOpenTimeSpan超时时间为 System.ServiceModel.Channel.CommunicationObject.OpenTimeSpan System.ServiceModel.Channels.CommunicationObject.Open处超时 位于Microsoft.Tools.SvcHost.ServiceHostHelper.OpenServiceInfo 信息

您提到App.config-听起来您的服务是一个WCF服务库，您在IIS下托管。如果是这种情况，则需要将WCF配置部分从App.config复制到承载服务的IIS应用程序的Web.config

---

库不使用配置文件-它们使用调用应用程序的配置文件。

没错，我这样做了-我将编辑以添加上面完整的web.config。您使用服务文件更新的web.config是应用程序的web.config吗，或者调用服务的应用程序？调用服务的应用程序。将设置放在具有服务文件的IIS应用程序的Web.config中-正是IIS下的应用程序需要将AspNetCompatibilityEnabled设置为True。我这样做了。这仍然是同一个问题。

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