Wow, I have been banging my head against the wall for about 5+ days now. I have a WCF Service Application (Windows Services hosted), using net.tcp binding with Windows Authentication, running on a remote server. I created a test Windows client, added a service reference to my IDataService, then created a ChannelFactory for my proxy. When calling the service I receive an error "The socket connection was aborted..."


Any suggestions on what I have done wrong here?


Here is my Win code call (this is only test code):

// These setting are exactly as the web.config in the IDataService.
NetTcpBinding binding = new NetTcpBinding() ;
binding.TransactionFlow = false;
binding.PortSharingEnabled = true;
binding.Security.Transport.ProtectionLevel = System.Net.Security.ProtectionLevel.EncryptAndSign;
binding.Security.Transport.ClientCredentialType = TcpClientCredentialType.Windows;
binding.Security.Mode = SecurityMode.None;
binding.ReceiveTimeout = TimeSpan.MaxValue;
        
var endPointAddress = new EndpointAddress(new Uri("net.tcp://SOMESERVER:9000/OperationsDataService.DataService.svc"), new SpnEndpointIdentity("MYSERVICE/MyMachine"));

var proxy = ChannelFactory<idataservice>.CreateChannel(binding, endPointAddress);

// SpParameter is a [DataContract] class in the WCF interface service that has a few [DataMembers].
SpParameter[] spParams = new SpParameter[1];
spParams[0] = new SpParameter();
spParams[0].Paraname = @"@Commodity";
spParams[0].Paratype = @"char(1)";
spParams[0].Paravalue = @"'P'";

// The proxy method returns a [DataContract] called ReturnResults which is basically a DataSet.  This DataSet gets added into the grid cntrol.
dataGridViewReturn.DataSource = proxy.ExecuteStoredProcedure("PowerTrading_Dev_I", "", spParams, true);

My web.config:

Do you have access to the WCF service & associated source code? Are you able to debug both sides of the call? (I ask because I'm wondering if there is an unhandled exception in the service which may be causing the abort.)

Also, have you tried WCF Storm or WireShark to manually test the call and/or sniff the traffic in-flight to see if you can get an idea of where it might be failing?

I would start with WCF Storm and try making the WCF service call to see if that part of the equation is even working. At least you cut in half the locations where the problem can be.

You are most likely getting a size limit on your data.

Try adding the dataContractSerializer service behaviour:

XML
<servicebehaviors>
 <behavior>
          <datacontractserializer maxitemsinobjectgraph="2147483647" />
          ....
        </behavior>
...
</servicebehaviors>
