Hello all,

We need to execute some code after a WCF method has finished and its reply
message is prepared.
The last thing we tried was to use an attribute which implements
IServiceBehavior and in ApplyDispatchBehavior we add a message inspector (a
class that implements IDispatchMessageInspector).
Unfortunately BeforeSendReply method is invoked proir to the serialization
of the returned objects. We need to execute some code after the
serialization - to be specific we are trying to close an NHibernate session
with Lazy Loading enabled.
Does anyone have an idea of how we can get called at the point when the
reply message is serialized?

Thanks in advance.

Hello, Stephan!

Have a look at this

Hi Vadym,

Unfortunately the proposed article does not mention interception points on
the way back from the server to the client. We presume that the mechanism is
somewhat similar to the one described in the article, but still there are no
examples. We couldn't figure out how to handle our problem.

Best regards.

Hello, Stephan!

Here are the links that show some of WCF extensibility points

Thank you for the help Vadim,

I have implemented IInputSessionShutdown. Now everything works fine.

Best regards,
