We've updated the MDbg source sample (download here) for Visual Studio 2005. This latest round of updates includes an integrated IL view, making the UI thread STA, fixing some build problems with VS2005 RTM and C# Express.
It took me under 3 minutes to downloaded it and build it all from scratch.
And just for kicks (and because I already have the jpg lying around), here's a screenshot of the GUI with integrated IL view:
Kudos to the usual suspects (Nick Hertl, Jan Stranik, Rick Byers, Jon Langdon)!
