My TechEd presentation “Common Issues in ASP.NET and how to debug them with Windbg” is now up on channel 9, so if you want to watch it, here you go http://channel9.msdn.com/posts/MSDNSweden/Vanliga-fel-som-grs-med-ASPNET-och-hur-du-hittar-dem-med-WinDbg/ Have fun, Tess

This is way out of the scope of what I normally troubleshoot, but I have gotten some questions around this and I just wanted to point out a really good resource (By Raffaele Limosani), for troubleshooting memory leaks in these kind of applications. http://blogs.msdn.com/raffael/archive/2008/02/21/netcf-memory-leak-now-what.aspx

There’s been close to 25 000 downloads of the buggy bits lab set , YAY!!! :)  but now I think it’s time to expand it a bit with some new labs.  I have a few different issues in mind but I wanted to check in and see if there is something specific you want to see in the new lab set.  I know that the first request I’ll probably get is to include something about COM debugging or debugging RCW/CCW leaks and I might do that, but I just want to say that I am struggling a bit with this. ...

... and here are the slides for the interactive session

I still have to figure out a way to host the video from the break-out session but until then, here are the slides for my presentations (attached). And here are a list of some of the tools and resources I used for the presentations Tool/Resource Comment Download Link Debugging Tools for windows Windbg, adplus etc. http://www.microsoft.com/whdc/devtools/debugging/default.mspx Debug Diag 1.1 Analyzes dumps, good for native memory leaks http://www.microsoft...

I'm back from TechEd in Barcelona, and it was one of the most fun, scary and humbling roller coaster rides I have ever been on. I am a bit of a glutton for punishment becuase I signed up to do two sessions and before I knew it I was scheduled to do one in the auditorium (on the largest stage I have ever seen, 760 sq ft). Not only that, but when I got to Barcelona they had scheduled me to do a repeat of the interactive session. I really do appreciate all the people that showed up at my sessions...

You learn something new every day… I was working on an issue with appdomain restarts caused by page re-compilations because aspx pages were created and modified from the code. You can get lifetime event information such as shutdown reasons, compilation information etc. in the eventlog by enabling Application Life Time Events in your web.config (See this post for more info about this and application restarts in general) We were seeing a lot of the following messages EventID: 1305 Event...

Mike Stall just wrote a very interesting post about ICoreDebug announcements at the PDC.  More specifically that ICoreDbg for 4.0 will support dump debugging which means that ICoreDebug based debuggers (eg. Visual Studio) will also be able to support this.  This is the best news I’ve heard in a long long time:) since it means that we can do post-mortem debugging in a bit more familiar environment than windbg (which is currently the tool of choice for this). Unfortunately I wasn’t at the...
