One of the things I showed at Directions US 2009 was how to send data to NAV via a XMLPort, and I promised to blog about that as well. In the meantime I found out, that Lars actually already wrote about this (and he also made a WebCast).
Please have a look at the NAV Team Blog for more info:
The only reason for this post is, that people who attended my session at Directions might look for stuff like this on my blog – so, here you are.
