Yesterday I ran headlong into a bug in Visual Studio 2005 – most of my keyboard shortcuts quit working. It wasn’t just an annoyance; it stopped me in my tracks. No editing, no saving, no anything. I know that ReSharper takes over most of the VS keyboard mappings so I uninstalled it, with no luck. Some googling led me to a pretty simple workaround: run devenv.exe from the command prompt with the /resetuserdata switch. It’s not a fix but it’s good enough for now. Apparently this problem has been around for some time, so I guess I’ve just been lucky until yesterday.
