    <p>I received callback interface from machine A and stored it on machine B. </p> <p>I'd like to pass this callback interface (that is a proxy on machine B) to machine C.</p> <p>Machines A, B and C uses WCF so proper interfaces are available.</p> <p>The issue is when I run PassCallbackToDedicatedMachine(someCallback) method I receive exception like below:</p> <p>Unable to cast object of type 'System.Object' to type 'HCP.Common.IClientApplicationCallback'.</p> <p>When I run method on a callback proxy on Machine B everything is ok.</p> <p>The problem is when I try to pass this callback (assigned to some WCF interface of course) to another machine.</p> <p>Maybe there is some method to obtain client endpoint address from proxy, pass this address as string and manually instantiate it on different machine (that knows this interface also).</p> <p>How to do it?</p> <p>Thanks,</p> <p>The callstack is below (maybe it will be helpful):</p> <p>at System.ServiceModel.Channels.ServiceChannel.ThrowIfFaultUnderstood(Message reply, MessageFault fault, String action, MessageVersion version, FaultConverter faultConverter)</p> <p>at System.ServiceModel.Channels.ServiceChannel.HandleReply(ProxyOperationRuntime operation, ProxyRpc&amp; rpc)</p> <p>at System.ServiceModel.Channels.ServiceChannel.Call(String action, Boolean oneway, ProxyOperationRuntime operation, Object[] ins, Object[] outs, TimeSpan timeout)</p> <p>at System.ServiceModel.Channels.ServiceChannel.Call(String action, Boolean oneway, ProxyOperationRuntime operation, Object[] ins, Object[] outs)</p> <p>at System.ServiceModel.Channels.ServiceChannelProxy.InvokeService(IMethodCallMessage methodCall, ProxyOperationRuntime operation)</p> <p>at System.ServiceModel.Channels.ServiceChannelProxy.Invoke(IMessage message)</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.
