    <p>I'm new to Silverlight and WCF services. I'm trying to write a client application that can manipulate an object server side. </p> <p>My problem is that each time my Silverlight client makes a call to the service, it enters into the constructor systematically</p> <pre><code>public SilverLightEnabledWcfService() { } </code></pre> <p>In the below example, I simply want to increment or decrement a number depending on the activity client side. </p> <p>How am I supposed to do this properly?</p> <p>I also tried to create a regular ASP.net client page and I got the same result, ie the server doesn't remember the session. So I don't think the problem is in my client, but I'm still happy to post the code if it helps.</p> <p>Thanks !!</p> <pre><code>using System; using System.Linq; using System.Runtime.Serialization; using System.ServiceModel; using System.ServiceModel.Activation; using Count.Library; namespace Count.WebApp { [ServiceContract(Namespace = "")] [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerSession)] [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)] public class SilverLightEnabledWcfService { public SilverLightEnabledWcfService() { } private Class1 _class1; [OperationContract] public int Add1() { if (_class1 == null) _class1 = new Class1(0); _class1.Add1(); return Value; } [OperationContract] public int Remove1() { if (_class1 == null) _class1 = new Class1(0); _class1.Remove1(); return Value; } public int Value { get { return _class1.Count; } } } } </code></pre>

    1. COWhat binding are you using? How do your server and client side config look like? Sessions are only supported on a select few bindings - most notably, the default basicHttpBinding does **not** support sessions....

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.
