I guess I am finding some value in using Twitter. Scott Gu (@scottgu) tweeted about this and pointing to a link to a video with Scott Hanselmann (@shanselman):
This looks to be a really fantastic feature of VS2010! Basically, you can force a dump of a process, and if you have the source on your machine, you can basically look at that snapshot-in-time, using your regular debugging tools (watch, right-clicking on a variable, etc). So no more SOS or other cryptic, unmanaged debugging tools. Very, very cool!!
