Silverlight 4 WCF RIA Service Timeout Problem

Question

I have a Silverlight 4 user control that calls a very long WCF RIA service. As shown below, I increase the default wait period.

_domainContext = new WindowsDashboardDomainContext();
// Increase timeout -- this can be a very long running query
((WebDomainClient<WindowsDashboardDomainContext.IWindowsDashboardDomainServiceContract>)
_domainContext.DomainClient).ChannelFactory.Endpoint.Binding.SendTimeout = new TimeSpan(99, 0, 0);
    _domainContext.GetSections( "All", "All", "All" ).Completed += GetAllSectionsCompleted;

Unfortunately, it seems to ignore this timeout and still throw a timeout exception:

Error: Unhandled error in Silverlight application. Error loading application for request "GetClicks". An error occurred while executing the command definition. See Internal Exception for more details. Internal exception message: Timeout. The wait period expires before the operation is completed or the server is not responding. in System.Data.EntityClient.EntityCommandDefinition.ExecuteStoreCommands (EntityCommand entityCommand, CommandBehavior behavior)

Why is this happening?

        {
            throw new InvalidOperationException(
              "There is no 'ChannelFactory' property on the DomainClient.");
        }

        ChannelFactory factory = (ChannelFactory)channelFactoryProperty.GetValue(this.DomainClient, null);

        factory.Endpoint.Binding.SendTimeout = new TimeSpan(0, 10, 0); 

    }
}
