    <p>I have a silverlight application which has a WCF in it. Since it is a self hosted WCF I've understand I have to add an interface something like:</p> <pre><code>[ServiceContract] public interface IPolicyRetriever { [OperationContract, WebGet(UriTemplate = "/clientaccesspolicy.xml")] Stream GetSilverlightPolicy(); [OperationContract, WebGet(UriTemplate = "/crossdomain.xml")] Stream GetFlashPolicy(); } </code></pre> <p>and the implemetation:</p> <pre><code>Stream StringToStream(string result) { WebOperationContext.Current.OutgoingResponse.ContentType = "application/xml"; return new MemoryStream(Encoding.UTF8.GetBytes(result)); } public Stream GetSilverlightPolicy() { string result = @"&lt;?xml version=""1.0"" encoding=""utf-8""?&gt; &lt;access-policy&gt; &lt;cross-domain-access&gt; &lt;policy&gt; &lt;allow-from http-request-headers=""*""&gt; &lt;domain uri=""*""/&gt; &lt;/allow-from&gt; &lt;grant-to&gt; &lt;resource path=""/"" include-subpaths=""true""/&gt; &lt;/grant-to&gt; &lt;/policy&gt; &lt;/cross-domain-access&gt; &lt;/access-policy&gt;"; return StringToStream(result); } public Stream GetFlashPolicy() { string result = @"&lt;?xml version=""1.0""?&gt; &lt;!DOCTYPE cross-domain-policy SYSTEM ""http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd""&gt; &lt;cross-domain-policy&gt; &lt;allow-access-from domain=""*"" /&gt; &lt;/cross-domain-policy&gt;"; return StringToStream(result); } </code></pre> <p>but I don't understand the next steps I have to do in order the silverlight calls to WCF will not raise communcation exception.</p> <p>Can you please show me the code I have to write and where? (when I google it I didn't understand when the WCF calls to retrive the clientaccesspolicy, and what is the endpoint I have to add, I'm new to silverlight and WCF and don't know exaclty why I have to add an endpoint...)</p> <p>this is my ServiceReference.ClientConfig:</p> <pre><code> &lt;configuration&gt; &lt;system.serviceModel&gt; &lt;bindings&gt; &lt;basicHttpBinding&gt; &lt;binding name="BasicHttpBinding_IMapService" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647"&gt; &lt;security mode="None" /&gt; &lt;/binding&gt; &lt;/basicHttpBinding&gt; &lt;/bindings&gt; &lt;client&gt; &lt;endpoint address="http://localhost:4693/MapService.svc" binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IMapService" contract="MapService.IMapService" name="BasicHttpBinding_IMapService" /&gt; &lt;/client&gt; &lt;/system.serviceModel&gt; &lt;/configuration&gt; </code></pre> <p>thank you!</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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
