In Visual Studio 2008, I periodically see the error in the status bar:
”Error updating JScript Intellisense, see Error list”
HOWEVER, there are no errors about this in the Error list! And, the site compiles, runs, and publishes perfectly! Total annoyance!
I believe this is an error caused by the inclusion of the JQuery library and some inability of the Intellisense parser to “play nice in the playground”.
Okay, so what’s the [workaround]?
You can force an update of Intellisense with the following keyboard-shortcut:
Ctrl + Shift + J
And Voila! Problem Solved! Annoyance gone!
