I'm not sure of the official release date but I would love to help track down the source of the lockup.
If you would like to get help resolving this issue please feel free to contact me at email@example.com.
We've fixed a large number of compiler crashes and many other product issues for VS2008.
I can't promise that all your problems have been fixed BUT I can promise that if you encounter any them (or even new VB related product issues) that we will investigate them.
I suspect you will be pleasantly surprised by the improvements in VS2008. If you do try the product and find any issues please contact us at
Since you are referring to an Intellisense file I'm going to assume you mean C++.
The performance improvements listed above refer to Visual Basic and I'm happy to report that for VB the Intellisense story is much improved. We have move some of the expensive first time loading of Intellisense off the UI thread and onto a background thread.
This results in a much more responsive UI (the way it should be).
As for C++, try out the VS2008 Beta and if you still see performance issues with Intellisense let them know at
Unfortunately we can't make any promises about which performance improvements will be ported back to VS2005.
However we are addressing this on a case by case basis and we may have some hotfixes soon that address some of these issues.
I'll try and post an update to this when I have more info.
I can't really speak for the C++ improvements too much although I understand that they made some significant improvements to Intellisense for 2008.
I would highly recommend you try out your solution with the Beta2 release now that it's available. If you still see performance issues please contact the C++ performance team directly at
