i use 3 beta. follow is code:

silverlight  enable WCF :

[ServiceContract(Namespace = "sunnhoo.Service")]
[AspNetCompatibilityRequirements(RequirementsMode =

AspNetCompatibilityRequirementsMode.Allowed)]
public class ChatService
{
[OperationContract]
public string GetChat(string owenerID, string userID)
{
     //...
     return "";
}

silverlight enable config:
<serviceBehaviors>
 <behavior name="ChatServiceBehavior">
     <serviceMetadata httpGetEnabled="true" />
     <serviceDebug includeExceptionDetailInFaults="false" />
    </behavior>
   </serviceBehaviors>
  </behaviors>
 <customBinding>
    <binding name="customBinding1">
     <binaryMessageEncoding />
     <httpTransport />
    </binding>
   </customBinding>
 <service behaviorConfiguration="ChatServiceBehavior" name="ChatService">
    <endpoint address="" binding="customBinding" bindingConfiguration="customBinding1"
     contract="ChatService" />
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
   </service>

and seems i cann't use jquery get touch with WCF Service.
and then , i create a new website and new Service ,
Ajax WCF Service:
[ServiceContract(Namespace = "")]
[AspNetCompatibilityRequirements(RequirementsMode =

AspNetCompatibilityRequirementsMode.Allowed)]
public class SSSSService
{
 // 添加 [WebGet] 属性以使用 HTTP GET
 [OperationContract]
    public string GetChat()
    {
        try
        {
            ChatService.ChatService service = new ChatService.ChatService();
            return service.GetChat("23", "23");
        }
        catch (Exception err)
        {
            return err.ToString();
        }
    }

    [OperationContract]
    public string ConnectionTest()
    {
        return "jQuery client connected to WCF service via AJAX";
    }
}

i use jquery get the data for Method ConnectionTest,
but get exception for Method GetChat :Unsupported Media Type.
