Hello,
It´s been a while since my last post.
I´ve decided to start a new topic regarding debugging posts. It´s called quick tips debugging code and here is my first post on the series.
Sometimes while debugging an issue I have to related different threads. (E.g: on a thread there is a reference to another thread object). So the question is: how to easily identify a thread in a thread object ? Below is the result of issuing !do on a thread object ( my sample is based on clr2.0) 0:777> !do 00000000c0559e38
