The guys call me a regular now, and I suppose I am. Here’s another hour of rambling and fun covering Vista (especially the Vista Bridge) the Vista things you’re not allowed to implement in managed code, C++, the MFC update, concurrency, and whatever else popped into my head while we were talking.

Imagine you have a bug that happens only in production. You connect to the production server and do a whole pile of exploring, and now you think you know what you need to tweak on your dev box to reproduce the problem and get started on fixing it. Or perhaps you are half way through figuring something out on your own machine and you need to hand over to another developer. Maybe you just want to switch to your laptop because you’re leaving the office. There are many reasons why you might want to copy breakpoints between computers. As you may know, they are kept in a .SUO file (Solution User Options I believe) in your solution folder.
But heavens above, do not try to copy that file from one machine to another! As John Robbins says:
The .SUO file is the bane of your existence. Nearly all the problems you encounter with Visual Studio are the result of a corrupt .SUO file. Sadly, it seems all it takes to corrupt the .SUO file is your heart beating. In other words, whenever you have Visual Studio crash, refuse to debug, or behave strangely it's the .SUO file's fault. Whenever anyone asks me about strange Visual Studio behavior, my instantaneous response is "Delete the .SUO!"
So John took care of this with his own add-in. You can save a set of breakpoints into a little file. You can then move the file between machines and use it to set all those same breakpoints on another machine. Or, probably even more fun, you can set aside the 20-some breakpoints, tracepoints, conditionals and so on that you painstakingly set up for bug A, save them and then clear them all, set different ones for the drop-everything-urgent bug B, and then when B is fixed you can get all your old breakpoints back and return to working on A. John is giving the add-in away, it works for both native and managed code, so go on, get it now.

One of the persistent myths of managed code is that you can’t have a memory leak if you’re a C# or VB developer. You really can. In this intriguing post, Sasha Goldshtein asks "Is it a managed or a native memory leak?" and then shows you some clues to lead you towards an answer.

While I was at Tech Ed Developers (US) this summer, I spoke with Craig Shoemaker for his Pixel8 podcast. We talk about UI, and Vista, and the usual things. I have some distinguished company in this interview but if you don’t want to listen to Ted Neward you can zip ahead to the 18 minute mark for me.

In case you were worried that Microsoft efforts like the Parallel Framework (PFX) would be aimed only at managed developers, leaving native developers sitting at the little kids table again, take a look at the Parallel Programming in Native Code blog. It hasn’t been updated terribly often, but perhaps some feedback would encourage them (or is it just Rick?) to keep it current . The one downer: "this is technology we're currently exploring and I don't have any ship or CTP dates to announce." Stay tuned, I suppose.

Tech Ed Developers (Europe) is spotlighting a number of the top sessions from last year, free for anyone to watch. Mark Russinovich (on Wikipedia, his blog) knows more about the internals of Windows than anyone else who’s allowed out in public, and in this session, The Case of the Unexplained... (rated 5 stars out of 5 by attendees), he covers various mystery bugs and how he tracked them down. I’m slightly disappointed that some of the stories ended "so I logged a bug with that team" – I would have loved it if these were all fix-your-config stories, but still to see the techniques is very cool, and if your own code is causing the mystery CPU spike or resource leak, you will really benefit from the tools and approaches Mark shows. Sure, it was at the IT Pro half of Tech Ed, but developers need to know this stuff too!
I would like this stage someday. It's the Barcelona keynote stage, used for wildly popular breakouts also.

I enjoyed meeting some friends from the C++ team at Tech Ed and taking a turn in the booth. Li Shao and Marian Luparu were there when I was, and plenty of customers came by. Now you can read a nice summary of the customer conversations on the C++ team blog. The comments keep the conversation going. They are reading, so go ahead and join in!
