    <p>I am receiving the following error on a WCF call:</p> <blockquote> <p>Maximum number of items that can be serialized or deserialized in an object graph is '65536'</p> </blockquote> <p>I've read a ton of forum posts and many of them mention modifying the app.config and web.config to specify new behavior to allow larger object graphs. I've done that and this is what I have in those files:</p> <p><strong>App.Config on the WPF project:</strong></p> <pre><code>&lt;system.serviceModel&gt; &lt;behaviors&gt; &lt;serviceBehaviors&gt; &lt;behavior name=""&gt; &lt;serviceMetadata httpGetEnabled="false" /&gt; &lt;serviceDebug includeExceptionDetailInFaults="false" /&gt; &lt;/behavior&gt; &lt;/serviceBehaviors&gt; &lt;endpointBehaviors&gt; &lt;behavior name=""&gt; &lt;dataContractSerializer maxItemsInObjectGraph="2147483646"/&gt; &lt;/behavior&gt; &lt;/endpointBehaviors&gt; &lt;/behaviors&gt; &lt;services&gt; &lt;service name="digiPM.Shell.LogOutPMSEMRService.PMSEMRLogOutService"&gt; &lt;!--&lt;endpoint address="" binding="basicHttpBinding" contract="digiPM.Shell.LogOutPMSEMRService.IPMSEMRLogOutService"&gt; &lt;identity&gt; &lt;dns value="localhost" /&gt; &lt;/identity&gt; &lt;/endpoint&gt; &lt;endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /&gt; &lt;host&gt; &lt;baseAddresses&gt; &lt;add baseAddress="http://localhost:8732/Design_Time_Addresses/digiPM.Shell.LogOutPMSEMRService/PMSEMRLogOutService/" /&gt; &lt;/baseAddresses&gt; &lt;/host&gt;--&gt; &lt;endpoint address="" binding="netTcpBinding" name="NetTcpBindingEndpoint" contract="digiPM.Shell.LogOutPMSEMRService.IPMSEMRLogOutService"&gt; &lt;identity&gt; &lt;dns value="localhost" /&gt; &lt;/identity&gt; &lt;/endpoint&gt; &lt;endpoint address="mex" binding="mexTcpBinding" bindingConfiguration="" name="MexTcpBidingEndpoint" contract="IMetadataExchange" /&gt; &lt;host&gt; &lt;baseAddresses&gt; &lt;add baseAddress="net.tcp://localhost:8732/Design_Time_Addresses/digiPM.Shell.LogOutPMSEMRService/PMSEMRLogOutService/" /&gt; &lt;/baseAddresses&gt; &lt;/host&gt; &lt;/service&gt; &lt;/services&gt; &lt;!--binding info - removed this for the sake of readability for this post --&gt; </code></pre> <p><strong>web.config on the service project:</strong></p> <pre><code>&lt;system.serviceModel&gt; &lt;bindings&gt; &lt;wsHttpBinding&gt; &lt;binding name="WSHttpBinding_Services" closeTimeout="01:10:00" openTimeout="01:10:00" receiveTimeout="01:10:00" sendTimeout="01:10:00" bypassProxyOnLocal="false" transactionFlow="false" hostNameComparisonMode="StrongWildcard" maxBufferPoolSize="524288" maxReceivedMessageSize="2147483647" messageEncoding="Mtom" textEncoding="utf-8" useDefaultWebProxy="true" allowCookies="false"&gt; &lt;readerQuotas maxDepth="4096" maxStringContentLength="2147483647" maxArrayLength="524288" maxBytesPerRead="524288" maxNameTableCharCount="524288" /&gt; &lt;reliableSession ordered="true" inactivityTimeout="01:10:00" enabled="false" /&gt; &lt;security mode="None"&gt; &lt;/security&gt; &lt;/binding&gt; &lt;/wsHttpBinding&gt; &lt;/bindings&gt; &lt;behaviors&gt; &lt;serviceBehaviors&gt; &lt;behavior name="digiPM.Service.Behavior"&gt; &lt;serviceMetadata httpGetEnabled="true" /&gt; &lt;serviceDebug includeExceptionDetailInFaults="false" /&gt; &lt;dataContractSerializer maxItemsInObjectGraph="2147483647" /&gt; &lt;/behavior&gt; &lt;/serviceBehaviors&gt; &lt;endpointBehaviors&gt; &lt;behavior name="customObjectQuota"&gt; &lt;dataContractSerializer maxItemsInObjectGraph="2147483646"/&gt; &lt;/behavior&gt; &lt;/endpointBehaviors&gt; &lt;/behaviors&gt; &lt;services&gt; &lt;service behaviorConfiguration="digiPM.Service.Behavior" name="digiPM.Service.AddressCrudService"&gt; &lt;endpoint address="" binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_Services" name="AddressCrudServiceEndPoint" bindingNamespace="urn:Dawliasoft.Sculpture" contract="digiPM.Services.Contracts.IAddressCrudService" behaviorConfiguration="customObjectQuota" /&gt; &lt;endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" behaviorConfiguration="customObjectQuota" /&gt; &lt;/service&gt; &lt;!--&lt;more services defined with same configuration as above..&gt;--&gt; &lt;/services&gt; &lt;/system.serviceModel&gt; </code></pre> <p>This, however, hasn't helped. Note that the services referenced in the APP.CONFIG are not the services I am having issues with.</p> <p>I've also tried the following:</p> <ul> <li><p>added these attributes to the service implementation: [DataContract(IsReference=true)], [ServiceBehavior(AddressFilterMode = AddressFilterMode.Any, MaxItemsInObjectGraph = 2147483646)]</p></li> <li><p>wrote a custom DataContractSerializerOperationBehavior class that set MaximumObjectsInGraph and IsReference behavior. Also added custom Attribute to apply this the service implementations. For the sake of clutter, I didn't post the code, but can add it if anyone thinks it would be beneficial.</p></li> </ul> <p>Thoughts? Ideas? Where do I go from here?</p> <p>Thanks in advance!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
