    <p>I have a WFC(4.0) service dll for which I have to create a host application. The dll is pretty simple and has the following interfaces:</p> <pre><code> [ServiceContract(CallbackContract=typeof(IChatServiceCallback))] public interface IService { [OperationContract] Guid Subscribe(); } public interface IServiceCallback { void NotifyClient(strign message); } </code></pre> <p>My problem comes when I try to create a service. When I create a channel from the client to the host, I get the following exception: <i>"The InstanceContext provided to the ChannelFactory contains a UserObjecct that does not implement the CallbackContractType 'Client.MyServiceReference.IServiceCallback'."</i></p> <p>I found that in the ServiceReference object browser the ClientObject does not contain the IServiceCallback interface. Here my correspoding host code:</p> <pre><code> ServiceHost host = new ServiceHost(typeof(ChatService)); try { host.BeginOpen(new AsyncCallback(OnOpen), host); mre.WaitOne(); if (host.State == CommunicationState.Opened) { Console.WriteLine("Server is running!\nServer listens on the following endpoints:"); foreach (var endp in host.Description.Endpoints) { Console.WriteLine("\t{0}", endp.Address); } Console.WriteLine("Press &lt;Enter&gt; to stop the server..."); Console.ReadLine(); host.Close(); } } catch (Exception ex) { Console.WriteLine("Error: {0}", ex.Message); } </code></pre> <p>How can I create a host application for a Service dll which contains callback interface that is implemented on the client side?</p> <p>ClientSide: try { clientID = client.Subscribe(); &lt;-- Throws exception. } catch(Exception ex) { MessageBox.Show(ex.Message, "Error", MessageBoxButton.OK); }</p>

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.
