I was talking about memory management issues -- and diagnosis with simple tools today. I promised to post an entry with the location of the various tools I mentioned and here it is:
You can get information on windbg at this location.Vadump has usage information and a download from msdn and microsoft.com respectively.
If those links break, searching for windbg and vadump on the microsoft.com home page gave good results, that's how I got those links in the first place.
CLR Profiler is available here and for Beta2+ here.
It comes with documentation but there is additional material available in the Performance PAG in Chapter 13.
You can get my LogDump tool from my blog here.
Thanks for coming!
