Question about Silverlight application debug

   Hi
I'm new in devforce & i've created a simple project using devforce 2010 for silverlight 4 (I've created my project using devforce silverlight application template).
Then i added a simple data object to my web application using entity data model wizard. this model has created successfully & devforce is integrated with it as shown in develpement guide. my entity container name (as my entity manager name) TestEntities.
This is my web.config file :

<?xml version="1.0" encoding="utf-8"?>

<configuration>

<configSections>

<section name="ideablade.configuration" type="IdeaBlade.Core.Configuration.IdeaBladeSection, IdeaBlade.Core" />

</configSections>

<ideablade.configuration version="6.00" xmlns="http://schemas.ideablade.com/2010/IdeaBladeConfig">

<logging logFile="log\DebugLog.xml" />

<!-- Additional configuration can be added to override defaults.

See the sample config files in the Learning Resources for more information.
-->

</ideablade.configuration>

<system.serviceModel>

<serviceHostingEnvironment aspNetCompatibilityEnabled="false" />

<!-- You can add Service definitions to override the default configuration.

See the sample config files in the Learning Resources for more information.
-->

<services>

<service name="EntityService" behaviorConfiguration="EntityServiceBehaviors" >

<!-- Add the following endpoint. -->

<endpoint contract="IMetadataExchange" binding="mexHttpBinding" address="mex" />

</service>

</services>

<behaviors>

<serviceBehaviors>

<behavior name="EntityServiceBehaviors" >

<serviceMetadata httpGetEnabled="true" />

</behavior>

</serviceBehaviors>

</behaviors>

</system.serviceModel>

<system.web>

<compilation debug="true" targetFramework="4.0">

<assemblies>

<add assembly="System.Data.Entity, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />

</assemblies>

</compilation>

</system.web>

<connectionStrings>

<add name="TestEntities" connectionString="metadata=res://*/TestTableModel.csdl|res://*/TestTableModel.ssdl|res://*/TestTableModel.msl;provider=System.Data.SqlClient;provider connection string=&quot;Data Source=EHSAN\SQLEXPRESS;Initial Catalog=Test;Integrated Security=True;MultipleActiveResultSets=True&quot;" providerName="System.Data.EntityClient" />

</connectionStrings>

</configuration>

& this is my App.config file (there was no app.config file in silverlight application by default & I added it manually)

<?xml version="1.0"?>

<ideablade.configuration version="6.00" xmlns="http://schemas.ideablade.com/2010/IdeaBladeConfig">

<logging logFile="DebugLog.xml"/>

<objectServer remoteBaseURL="http://localhost" serverPort="9009" serviceName="EntityService.svc" >

<clientSettings isDistributed="true" />

</objectServer>

</ideablade.configuration>

then I tried to create new entitymanager object in my silverlight application & query it using linq to devforce :

TestEntities mgr = new TestEntities();

var q = from r in mgr.testTables select r;
...

but when i execute my project, it just runs sccessfully but returns not result (my databse table is not empty), it seems there is no communication between client & server, because when i see IsConnected property of entitymanager object in debug mode, its always false (even then i pass should connect parameter to entitymanager constructor).
but i really dont know where is the problem, program is running without any error or warning . I've just this warning :
Warning 1 A custom tool '<RemoveToRestore>EntityModelCodeGenerator' is associated with file 'TreeTableModel.edmx', but the output of the custom tool was not found in the project.  You may try re-running the custom tool by right-clicking on the file in the Solution Explorer and choosing Run Custom Tool. 
but dont think it was the reason of my pronblem.
anybody can help me ?
