I'll be debugging a site in Visual Studio 2010 and editing an *.aspx or *.ascx file, and without warning, it will lock up so that I can't edit it. There's no message or anything, I just can't type or make any changes.
The only way to start editing again is to stop debugging, close the editing window, and then find whatever file I was working on and reopen it. It's a huge pain in the you-know-what.
My colleagues are experiencing the same thing, so it's apparently not something with my particular setup.
What's the explanation, and how can we make it stop?
Note 1: I've reported this to Microsoft here. If you've experienced this as well, please go there and vote up the bug report.
Note 2: This is not VSS-related, at least in my case. We use VisualSVN, which doesn't use file-system-level locking to mark files as checked out.
