We have GAX/GAT1.3 ready to ship. However, none of the p&p factories are implemented for Orcas at the moment. So, despite the fact that GAX/GAT is available for Orcas, you can only use it to build your own factories, not to run the ones shipped by p&p (i.e. Web Client Software Factory, Smart Client Software Factory, Web Service Software Factory, Mobile Client Software Factory). Those will only work on GAX 1.3 on VS2005.
It is very important for us to understand how the community uses GAX/GAT before we ship. Please tell us in this 1-question poll.
