我正在构建一个与现有应用程序对话的WCF服务，并且此应用程序需要访问ASP.NET会话 - 能够查看会话是我无法解决的要求。
我构建了WCF项目 - 并在App.config中进行了以下设置：
<system.serviceModel>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" />
我还在文件中包含了一个接口和服务实现。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，其中包含：
<%@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，我收到了这个错误：
“
System.InvalidOperationException：此服务需要ASP.NET 兼容性，必须在IIS中托管。要么托管服务 在web.config中启用了ASP.NET兼容性的IIS或设置 AspNetCompatibilityRequirementsAttribute.AspNetCompatibilityRequirementsMode 属性为Required以外的值。在 System.ServiceModel.Activation.AspNetEnvironment.ValidateCompatibilityRequirements（AspNetCompatibilityRequirementsMode compatibilityMode）at System.ServiceModel.Activation.AspNetCompatibilityRequirementsAttribute.System.ServiceModel.Description.IServiceBehavior.Validate（ServiceDescription description，ServiceHostBase serviceHostBase）at System.ServiceModel.Description.DispatcherBuilder.ValidateDescription（ServiceDescription description，ServiceHostBase serviceHost）at System.ServiceModel.Description.DispatcherBuilder.InitializeServiceHost（ServiceDescription description，ServiceHostBase serviceHost）at System.ServiceModel.ServiceHostBase.InitializeRuntime（）at System.ServiceModel.ServiceHostBase.OnBeginOpen（）at System.ServiceModel.ServiceHostBase.OnOpen（TimeSpan timeout）at System.ServiceModel.Channels.CommunicationObject.Open（时间跨度 System.ServiceModel.Channels.CommunicationObject.Open（）的超时） 在Microsoft.Tools.SvcHost.ServiceHostHelper.OpenService（ServiceInfo 信息）“

答案 0 :(得分：0)
你提到了App.config - 听起来你的服务是一个WCF服务库，你在IIS下托管。如果是这种情况，则需要将WCF配置部分从App.config复制到托管服务的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。
