I am a developer on the Biztalk RFID team. I have been on this team since its inception. Phew... it has been a long march!! But, I am excited about all the work we have put in being used in the "real" world.
One of the main areas of my work is "Asynchronous Event Processing" (so you know who to blame... :)). My posts will be centered around this topic. I also plan/hope to touch upon future directions of the product.
