Question

I use WCF service to connect WPF front-end application with ERP back-end database.

I get an WCF service error: “The connection was closed unexpectedly” in my WPF application when trying to load table with many records (about 1000). Everything is going fine on tables with 10 – 20 records.

In my settings of the WCF service I have nothing conserning TimeOut settings. Maybe there are some timeout settings by default. How I can change this?

This is code with settings of my WCF service:

public void Start()
    {
        BasicHttpBinding binding = new BasicHttpBinding();
        binding.Name = "NAVBinding";
        binding.HostNameComparisonMode = HostNameComparisonMode.StrongWildcard;
        Uri baseAddress = new Uri("http://localhost:8000/nav/customer");
        Customer_Service service = new Customer_Service();
        serviceHost = new ServiceHost(service, baseAddress);
        serviceHost.AddServiceEndpoint(typeof(ICustomer_Service), binding, baseAddress);
        OpenMetadataExchange(baseAddress);
        service.navEventListner = this;
        serviceHost.Open();
    }

The problem is likely that the response is exceeding either the MaxReceivedMessageSize property of the client binding or the reader quotas.
