    copied!<p>My Entity Framework model is generated from SQL Server database. Since I need to access database from Silverlight, I generated a DomainService for RIAServices against the EF model. <code>Product</code> is one of the autogenerated <code>EntityObject</code> corresponding to the table <code>Product</code>. I am attempting to pass the custom class <code>CompositeData</code> across to the Silverlight client as shown. The problem is that <code>CurrentProduct</code> field is not accessible in the client but the other string/int fields are accessible. How can make <code>CurrentProduct</code> accessible from client?</p> <pre><code>public class CompositeData { [Key] public Guid PKey { get; set; } public string CompositeName { get; set; } public string Identity { get; set; } public Product CurrentProduct { get; set; } //Product is an auto-generated EntityObject class public CompositeData() { PKey = Guid.NewGuid(); } } </code></pre> <p>Following is the Domain Service method:</p> <pre><code>[EnableClientAccess()] public class LocalDomainService : DomainService { public IEnumerable&lt;CompositeData&gt; GetData() { List&lt;CompositeData&gt; listData = new List&lt;CompositeData&gt;(); //... return listData; } } </code></pre> <p>From the Silverlight client, </p> <pre><code> domService.Load(domService.GetDataQuery(), GetDataCompleted, null); private void GetDataCompleted(LoadOperation&lt;CompositeData&gt; compData) { foreach(CompositeData cdItem in compData.Entities) { // cdItem.CompositeName is accessible // cdItem.CurrentProduct is not accessible! } } </code></pre> <p>EDIT: <code>Product</code> class is autogenerated in Model1.Designer.cs </p> <pre><code> [EdmEntityTypeAttribute(NamespaceName="MyDBModel", Name="Product")] [Serializable()] [DataContractAttribute(IsReference=true)] public partial class Product : EntityObject { //.. } </code></pre> <p>It gets generated in the client project also (in SilverlightProject.g.cs)</p> <pre><code> /// &lt;summary&gt; /// The 'Product' entity class. /// &lt;/summary&gt; [DataContract(Namespace="http://schemas.datacontract.org/2004/07/SilverlightProject")] public sealed partial class Product : Entity { //.. } </code></pre>
