    <p>I have the following structure:</p> <pre><code>public class DerivedClass : List&lt;BaseClass&gt; { //Some helper methods used against the List of BaseClass properties //Methods public List&lt;BaseClass&gt; GetListOfBaseClasses() { return (List&lt;BaseClass&gt;)this; } } </code></pre> <p>My WCF service knows about the BaseClass object, but the client derived it as a generic list, now when I try to call the service, like this:</p> <pre><code>DerivedClass classD; FillData(classD) List&lt;BaseClass&gt; baseClassList = classD.GetListOfBaseClasses(); using (IService myService = ObjectFactory.GetMyService()) { myService.DoSomething(baseClassList); //Method is expecting "List&lt;BaseClass&gt;" } </code></pre> <p>I get the following exception:</p> <blockquote> <p>Type 'DerivedClass' with data contract name '[some URI text]' is not expected. Consider using a DataContractResolver or add any types not known statically to the list of known types - for example, by using the KnownTypeAttribute attribute or by adding them to the list of known types passed to DataContractSerializer.</p> </blockquote> <p>I tried adding these attributes to my class in various combinations but still no luck:</p> <pre><code>[Serializable] [KnownType(typeof(List&lt;BaseClass&gt;))] [XmlInclude(typeof(List&lt;BaseClass&gt;))] [KnownType(typeof(BaseClass))] [XmlInclude(typeof(BaseClass))] public class DerivedClass : List&lt;BaseClass&gt; { /// ... } </code></pre> <p>PS- Sheehs, am I the only one that thinks the entry fields are funky on this site? Things keep moving around as I try to format... :| great site regardless of my inability to get the idea of entering text as I want. </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.
