I'm part way through developing an Excel Add-in in .NET for configuring an AF 2.x database (creating elements, linking elements, etc.) and things are going fairly well. The AF SDK seems very comprehensive (Office Interop is painful though).
We have not been able to manage with the AF 1.3 "PI-AF Configurator" and the compatibility layer as it only seems to understand composition references and nothing else.
It has occurred to me though that I might not be the only person who can't wait until 2011 for the AF 2.3's Excel configuration tool. Has anyone done anything similar already, and if so is there anything special I need to consider? Or is there another option for bulk loading data into the AF?
