【问题描述】：

我正在构建一个与现有应用程序对话的 WCF 服务，而此应用程序需要访问 ASP.NET 会话 - 查看会话的能力是我无法解决的要求。

我构建了 WCF 项目 - 并在 App.config 中有以下设置：

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

我还在文件中包含了服务的接口和实现。在实现之前，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

这是一个 REST 服务，所以我的界面开始如下：

// 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 - 在 SearchService.svc 文件中，该文件包含以下内容：

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

我将它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，我收到了这个错误：

"

System.InvalidOperationException：此服务需要 ASP.NET 兼容性，并且必须托管在 IIS 中。将服务托管在 在 web.config 中打开具有 ASP.NET 兼容性的 IIS 或设置 AspNetCompatibilityRequirementsAttribute.AspNetCompatibilityRequirementsMode 属性设置为必需以外的值。在 System.ServiceModel.Activation.AspNetEnvironment.ValidateCompatibilityRequirements（AspNetCompatibilityRequirementsMode 兼容性模式）在 System.ServiceModel.Activation.AspNetCompatibilityRequirementsAttribute.System.ServiceModel.Description.IServiceBehavior.Validate（ServiceDescription 描述，ServiceHostBase serviceHostBase) 在 System.ServiceModel.Description.DispatcherBuilder.ValidateDescription（ServiceDescription 描述，ServiceHostBase 服务主机）在 System.ServiceModel.Description.DispatcherBuilder.InitializeServiceHost（ServiceDescription 描述，ServiceHostBase 服务主机）在 System.ServiceModel.ServiceHostBase.InitializeRuntime() 在 System.ServiceModel.ServiceHostBase.OnBeginOpen() 在 System.ServiceModel.ServiceHostBase.OnOpen（时间跨度超时）在 System.ServiceModel.Channels.CommunicationObject.Open（时间跨度 超时）在 System.ServiceModel.Channels.CommunicationObject.Open() 在 Microsoft.Tools.SvcHost.ServiceHostHelper.OpenService（ServiceInfo 信息）”

【参考方案1】：

您提到了 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，您需要将 WCF 配置部分从 App.config 复制到托管您的服务的 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。

【讨论】：

是的，我这样做了 - 我将编辑以添加上面的完整 web.config。

你更新的 web.config 是应用程序的服务文件还是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 - 需要将 AspNetCompatabilityEnabled 设置为 True 的应用程序（在 IIS 下）。

我做到了。还是一样的问题。
