This is surely no surprise for many people: you can actually debug managed code with WinDbg (or CDB, if you prefer that one) by using the SOS extension (that ships with the .Net framework) in the debugger. What’s new is that today, Microsoft released Psscor2 which is pretty much an enhanced version of SOS. Now I’m sure that you’ll soon find much information on using Psscor2 on Tom’s blog. I’m much in favor of Psscor2 myself and therefore I’ll try to post useful scripts here as well (if I can come up with some ;-)).
