The underlying connection was closed: The connection was closed unexpectedly.” While returning Data Table from WCF service.

I have changed my operation Contract to return Dataset Instead of Data Table

[OperationContract]

DataSet LoadBatchInformation(string Batch);

Simple program using WCF
http://johnwsaunders3.wordpress.com/2009/05/17/how-to-consume-a-web-service/

The maximum message size quota for incoming messages (65536) has been exceeded. To increase the quota, use the MaxReceivedMessageSize property on the appropriate binding element.

I got this error

"The maximum message size quota for incoming messages (65536) has been exceeded. To increase the quota, use the MaxReceivedMessageSize property on the appropriate binding element."

when i received data from the server.
for this problem i set MaxReceivedMessageSize in my client side.

<wsHttpBinding>

    <binding name="test" closeTimeout="00:01:00" openTimeout="00:01:00"

     receiveTimeout="00:10:00" sendTimeout="00:01:00" bypassProxyOnLocal="false"

     transactionFlow="false" hostNameComparisonMode="StrongWildcard"

     maxBufferPoolSize="524288" maxReceivedMessageSize="2147483647" messageEncoding="Text"

     textEncoding="utf-8" useDefaultWebProxy="true" allowCookies="false">

(or)

WSHttpBinding binding = new WSHttpBinding();

            binding.MaxReceivedMessageSize = 2147483647;

            EndpointAddress endpointAddress = new EndpointAddress("http://localhost:59167/Service1.svc");

            ServiceReference1.Service1Client sc = new ServiceReference1.Service1Client(binding,endpointAddress);

Hope this helps.
