Hi all,
I'm a newbie to this newsgroup, so excuse me If I repeat
well-known things. Why the performance of unmanaged
debugging under VS.NET is so sluggish? I'm developing an
add-in for VS.NET, so I have to enable unmanaged
debugging from time to time to catch unmanaged exceptions.
With this option is turned on, the debuggee process
(devenv.exe) executes order of magnitude slower than
without it. Does anybody know is there any way to speed-
up unmanaged debugging with VS.NET? Or may be there is an
alternative debugger that allows debugging of mixed
managed/unmanaged code...

Thanks in advance,
Dmitry

Dmitry,

I wouldn't consider the slowdown of the VS.NET debugger "an order of
magnitude" greater, but if you are having problems you can try WinDBG. You
can get WinDBG from http://www.microsoft.com/whdc/ddk/debugging. WinDBG
supports both managed and unmanaged debugging and will be much quicker than
VS.NET since it's a much lighter application.

Thanks! Robert Gruen

Robert,
well, as for 'order of magnitude', may be I slightly
exaggerated, but enabling this option makes debugging of
large application (like VS.NET) almost impossible thing.

Thanks for reference to WinDBG. I didn't know that it
supports mixed debugging, I'll try it
