First, you can also turn on the WCF service tracing at server-side and collect some trace log to see the detailed error it logged and verify if the message size(or related quota limit) does be the cause of the problem.
#Service Trace Viewer Tool (SvcTraceViewer.exe)
For WCF service which need to accept large size data(in request message), there are several settings you need to take care:
* the maxReceivedMessageSize and other related attributes in the <binding> element. And yes, you need to specify the <binding> through "bindingConfiguration" attribute for both your service and client. And the <binding> setting at client
and service sides need to match.
* the <readerQuotas> setting (under <binding> element) which can specify some limitation of the underlying data reader(for processing underlying WCF messsages). e.g.
<basicHttpBinding> <binding name="xxx" maxBufferSize="10000000" maxBufferPoolSize="10000000" maxReceivedMessageSize="10000000"> <readerQuotas maxDepth="10000000" maxStringContentLength="10000000" maxArrayLength="10000000"
maxBytesPerRead="10000000" maxNameTableCharCount="10000000" /> </binding>
* the "maxItemsInObjectGraph" attribute in <dataContractSerializer> element. This one is for controlling the underlying DataContractSerializer in case your service will transfer complicated large data object. You can specify it under servicebehavior
<behaviors> <serviceBehaviors> <behavior name="Umea.se.EventReactor.ServiceTier.ServiceViewEventBehavior"> <serviceMetadata httpGetEnabled="true" /> <serviceDebug includeExceptionDetailInFaults="true" /> <dataContractSerializer
maxItemsInObjectGraph="2147483647" /> </behavior> </serviceBehaviors> </behaviors> </system.serviceModel>
* and the <httpRuntime> element which contains the maxRequestLength and executionTimeout attributes. This is necessary when you host your WCF http based service in ASP.NET/IIS environment.
For test purpose, you can set them to the max integer value as other members have suggested. I agree that sometimes such issue is really painful to troubleshoot, but you can try creating a simplified repro and then apply the above settings one by one to
hit the point.
