Tracking “active” clients using method parameter inspection in a WCF web service

I'm a managing partner of NoobitAR, a new software company based in Buenos Aires, Argentina. I'm always willing to learn new technologies, in order to improve our products, to help colleagues and customers with their challenges, and to contribute with the community based on my own experiences.
As a hobby, I produce electronic music, and practice martial arts (sipalki and muay thai).
