I'm probably completely wrong, but but am I right in thinking the problem is due Jrs::SmartPtr<T> and not the fact that VS.NET or the serialization library is not find the right serialize method. If so I'm surprised no one else has pointed this out before! It's clearly stated in the last string of emails that there is no serialize method defined for the smart pointer you are using, and therefore you need to write some code to serialise the smart pointer object that holds the message object. If you don't want to do this, and depending on the characteristics of your smart pointer class, and where/how it's referenced in your code (i.e. it could be as simple as changing a typedef and few other small pieces if you are lucky), you could try porting your code to use one of the boost smart pointers, such as boost::shared_ptr. Anyway, forgive me if I'm wrong, and totally missing the point. Oh, on a completely off-topic note, I just realised Marcin that you're only a few miles down the road from me. I'm in based in Bournemouth. Jason On 19 Me 2005, at 15:44, Marcin Tustin wrote:

I've been looking through the template instantiation trace, and I can't figure out where the choice to use the intrusive mechanism is made. I'll keep looking a little more, and I've appended the trace below:
