Using the powers of the debugger to solve the problems of the world - and a bag of chips by Tess Ferrandez, ASP.NET Escalation Engineer (Microsoft)
Tess Ferrandez
I work as a developer evangelist at Microsoft, and my job is to help developers make the most of their skills on the MS stack.
In this blog I share tips on anything from debugging and troubleshooting to development on platforms like Windows, Web, Windows Phone and Kinect. And also some random tidbits about computing and my life at MS.
If you are new here, start with:
My debugging labs (Buggy Bits)
My Silverlight labs (building a game)
XNA for Windows Phone Walkthrough (building a game)
Thanks for visiting my blog
