WCF problem in WPF: The underlying connection was closed

Question

I am using WCF Services in my WPF project. I have a large amount of data, about 847000 records in table. this exception is throwed on client side The underlying connection was closed: The connection was closed unexpectedly

Here is fragment of my code and config files:
proxy.ServicesClient client = new proxy.ServicesClient();
var result = client.GetCustomers(); // here throws ('ComunicationException was unhandled by user code: The underlying connection was closed: The connection was closed unexpectedly.')

In my app.config
<?xml version="1.0" encoding="utf-8" ?>
<configuration> 
    <system.serviceModel>
      <bindings>
        <basicHttpBinding>
          <binding name="BasicHttpBinding_IServices" closeTimeout="00:10:00"
              openTimeout="00:10:00" receiveTimeout="00:10:00" sendTimeout="00:10:00"

            <security mode="None" />
          </binding>
        </basicHttpBinding>

Did you have this problem on WCF Services?


Note: It dose not work with large amount of data. In this case I have about 847 000 records in table. It works with small data perfectly(with about 5000 - 6000 records)
