    <p>I am building a WCF service that speaks to an existing application, and this application requires access to ASP.NET sessions - the ability to see sessions is a requirement I cannot get around.</p> <p>I built the WCF project - and have the following setting in App.config:</p> <pre><code> &lt;system.serviceModel&gt; &lt;serviceHostingEnvironment aspNetCompatibilityEnabled="true" /&gt; </code></pre> <p>I also included an interface and an implementation of the service in the file. In front of the implementation I have:</p> <pre><code>// 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 { </code></pre> <p>This is a REST service, so my interface starts like:</p> <pre><code>// 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(); </code></pre> <p>The service itself is hosted in another web application - in a SearchService.svc file which has this:</p> <pre><code>&lt;%@ServiceHost language=c# Debug="true" Service="Altec.UI.Web.SearchService.SearchService" %&gt; </code></pre> <p>and I added this to the web.config of the hosting application:</p> <pre><code> &lt;system.serviceModel&gt; &lt;serviceHostingEnvironment aspNetCompatibilityEnabled="true"/&gt; </code></pre> <p>I believe I did all the right steps - and yet when I try to run the web application I get this error:</p> <blockquote> <p>"</p> <p>System.InvalidOperationException: This service requires ASP.NET compatibility and must be hosted in IIS. Either host the service in IIS with ASP.NET compatibility turned on in web.config or set the AspNetCompatibilityRequirementsAttribute.AspNetCompatibilityRequirementsMode property to a value other than Required. at 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(TimeSpan timeout) at System.ServiceModel.Channels.CommunicationObject.Open() at Microsoft.Tools.SvcHost.ServiceHostHelper.OpenService(ServiceInfo info)"</p> </blockquote> <pre><code> &lt;?xml version="1.0"?&gt; &lt;!-- For more information on how to configure your ASP.NET application, please visit http://go.microsoft.com/fwlink/?LinkId=169433 --&gt; &lt;configuration&gt; &lt;appSettings&gt; &lt;!-- database connection details --&gt; &lt;/appSettings&gt; &lt;system.web&gt; &lt;customErrors mode="Off"/&gt; &lt;compilation debug="true"&gt; &lt;assemblies&gt; &lt;add assembly="System.Design, Version=4.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A"/&gt; &lt;add assembly="System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A"/&gt; &lt;add assembly="System.Drawing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A"/&gt; &lt;add assembly="System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/&gt; &lt;/assemblies&gt; &lt;/compilation&gt; &lt;pages&gt; &lt;controls&gt; &lt;add tagPrefix="ajaxToolkit" assembly="AjaxControlToolkit" namespace="AjaxControlToolkit"/&gt; &lt;/controls&gt; &lt;/pages&gt; &lt;/system.web&gt; &lt;system.web.extensions&gt; &lt;scripting&gt; &lt;webServices&gt; &lt;jsonSerialization maxJsonLength="1048576"/&gt; &lt;/webServices&gt; &lt;/scripting&gt; &lt;/system.web.extensions&gt; &lt;location path="Scripts"&gt; &lt;system.web&gt; &lt;authorization&gt; &lt;allow users="*"/&gt; &lt;/authorization&gt; &lt;/system.web&gt; &lt;/location&gt; &lt;location path="Content"&gt; &lt;system.web&gt; &lt;authorization&gt; &lt;allow users="*"/&gt; &lt;/authorization&gt; &lt;/system.web&gt; &lt;/location&gt; &lt;location path="jQuery-UI-layout.css"&gt; &lt;system.web&gt; &lt;authorization&gt; &lt;allow users="*"/&gt; &lt;/authorization&gt; &lt;/system.web&gt; &lt;/location&gt; &lt;!-- When deploying the service library project, the content of the config file must be added to the host's app.config file.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
