We released VS 2010 RC on Monday and have seen some great feedback on performance and stability.
But one issue we've seen a few people encounter is Intellisense crashes that occur frequently on machines with UI Automation enabled and certain devices connected.
Crash Symptoms If you experience recurring VS 2010 crashes when the Intellisense window appears or disappears while you type in the editor, then you have this problem.
Why does the crash occur?
The most common cause of crashes is because of the machine you're running on:
It's a Tablet PC (even if you're not using a pen)
Multi-touch screen driver enabled Have an external input device like a pen or Wacom tablet Enabled screen reader The reason is that there was a very late patch just before the RC version was released that modified the UI input code path, which unfortunately caused this defect.
A patch to fix this problem is coming soon. We are working on a patch for the VS 2010 RC version, which we will release next week. This patch will correct this problem and prevent it from happening again. I'll provide a link to the patch on the blog once it's out.
Current Contingency Measures There are currently 2 contingency measures for this issue. One is to kill your tablet service (see this article for details) or kill the multi-touch/pen drive on your system. Another is to set a registry key.
You can read the details of these two workarounds in this blog post from the VS development team.
What if it still crashes?
If you're still seeing crashes after trying these steps (or crashing in non-Intellisense scenarios), please send me an email ( [email protected] ), we want to make sure we track down the issue you're experiencing. reasons and take follow-up measures.
Hope this article is helpful to you,
