When i change the OperationContract of my service operation to IsOneWay=true,
i now get this exception:
The CustomBinding on the ServiceEndpoint with contract 'IService1' lacks a
TransportBindingElement. Every binding must have at least one binding
element that derives from TransportBindingElement.

contractName)

My config looks like this:
<bindings>
<nmsBinding>
<binding name="myNMSBinding" destination="test.queue">
</binding>
</nmsBinding>
</bindings>
<extensions>
<bindingElementExtensions>
<add name="nmsTransPort" type="Apache.NMS.WCF.NmsTransportElement,
Apache.NMS.WCF, Version=1.1.0.1642, Culture=neutral,
PublicKeyToken=82756feee3957618" />
</bindingElementExtensions>
<bindingExtensions>
<add name="nmsBinding" type="Apache.NMS.WCF.NmsBindingCollection,
Apache.NMS.WCF, Version=1.1.0.1642, Culture=neutral,
PublicKeyToken=82756feee3957618" />
</bindingExtensions>
</extensions>
<endpoint address="tcp://johannes-xp:61616" binding="nmsBinding"
bindingConfiguration="myNMSBinding"
contract="WcfServiceLibrary2.IService1" />
I tried to add a <nmsTransPort/> into the binding, but then i get an unknown
element exception.
Anybody has clue whats wrong here?
Thanks, Johannes
