just got an IM from a person who attended my session on teched. on the session I showed how to use the sos debugger extension to analyze dump files, especially if you have problems on production environments.
he was able to track down a design problem of not having a dispose method along with it's Finalize, chris sells mentioned this not long ago on the DNR.
anyway it's great knowing people are actually using what you show, because it was a fairly low level stuff, windbg is not something easy to show, people like to see windows and graphics and not just dumps of memory.
I think I'm going to write some more about production time debugging in the next few days, especially on the problems you have when using the sos extension dll,
TIP of the day: did you know that you could use visual studio 2003 to load the clr v1.0 sos.dll ?
