WCF会话ASP.NET托管问题

Question

我正在构建一个与现有应用程序对话的WCF服务，这个应用程序需要访问ASP.NET会话--查看会话的能力是我无法回避的一个要求。

我构建了WCF项目--并在App.config中设置了以下设置：

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

我还在文件中包含了服务的接口和实现。在实施之前，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，所以我的接口启动如下：

// 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--在一个SearchService.svc文件中，该文件具有如下内容：

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

我将其添加到宿主应用程序的web.config中：

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

我相信我做了所有正确的步骤--然而，当我试图运行web应用程序时，我得到了以下错误：

“

System.InvalidOperationException:此服务需要ASP.NET兼容性，并且必须托管在IIS中。或者在IIS中承载具有在AspNetCompatibilityRequirementsAttribute.AspNetCompatibilityRequirementsMode中打开的ASP.NET兼容性的服务，或者将web.config属性设置为非必需的值。( System.ServiceModel.Activation.AspNetEnvironment.ValidateCompatibilityRequirements(AspNetCompatibilityRequirementsMode compatibilityMode)在System.ServiceModel.Activation.AspNetCompatibilityRequirementsAttribute.System.ServiceModel.Description.IServiceBehavior.Validate(ServiceDescription description，ServiceHostBase ServiceHostBase ( System.ServiceModel.Description.DispatcherBuilder.ValidateDescription(ServiceDescription description)，ServiceHostBase serviceHost( System.ServiceModel.Description.DispatcherBuilder.InitializeServiceHost(ServiceDescription description)( System.ServiceModel.ServiceHostBase.InitializeRuntime() at System.ServiceModel.ServiceHostBase.OnBeginOpen() at System.ServiceModel.ServiceHostBase.OnOpen(TimeSpan timeout) System.ServiceModel.Channels.CommunicationObject.Open(TimeSpan超时值( System.ServiceModel.Channels.CommunicationObject.Open() at Microsoft.Tools.SvcHost.ServiceHostHelper.OpenService(ServiceInfo info)

您提到了App.config --听起来您的服务是一个，您正在IIS下托管它。如果是这样的话，您需要将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。
