About Knowledgecast

My name is Arunjeet Singh and I work as a Microsoft field consultant. Knowledgecast is a place where I document my experiences as I learn new technology and get to grips with problems I come across in my day to day work. Whenever I learn something new I try and get it out (in as structured a way as possible) to the wider developer community. I guess this is my way of spreading the love :D
