Silverlight Faults

   MSDN Magazine has an article this month about handling Silverlight Faults.  It references the MSDN site: http://msdn.microsoft.com/en-us/library/dd470096(VS.95).aspx.

This code provides a simple Fault Behavior.  However, when I try to implement it, I get the dreaded Not Found error.  

Can we implement this?

Here's the Shell.Web's Web.config that doesn't work:

<system.serviceModel>

    <serviceHostingEnvironment aspNetCompatibilityEnabled="false" />

    <extensions>

      <behaviorExtensions>

        <add name="silverlightFaults"

             type="Png.Silverlight.Behaviors.SilverlightFaultBehavior, Png.Silverlight.Behaviors.FaultBehavior"/>

      </behaviorExtensions>

    </extensions>

    <diagnostics>

      <messageLogging logEntireMessage="true"></messageLogging>

    </diagnostics>

    <behaviors>

      <endpointBehaviors>

        <behavior name="SilverlightFaultBehavior">

          <silverlightFaults/>

        </behavior>

      </endpointBehaviors>

    </behaviors>

    <services>

      <service name="EntityService">

        <endpoint address="" binding="customBinding" bindingConfiguration="customBinaryBinding" contract="IdeaBlade.EntityModel.IEntityServiceContract" behaviorConfiguration="SilverlightFaultBehavior"/>

      </service>

      <service name="IdeaBlade.EntityModel.Server.EntityServer">

        <endpoint address="" binding="customBinding" bindingConfiguration="customBinaryBinding" contract="IdeaBlade.EntityModel.IEntityServerContract" behaviorConfiguration="SilverlightFaultBehavior"/>

      </service>

    </services>
