I am having a strange problem with IntelliSense in Visual Studio 2010 C# Express Edition: when it pops up to show me the list of suggestions, the list is missing valid options.
For example, say I want to add a “KeyDown” event handler to a control, I start typing “someControl.K<Ctrl+Space>“, but the popup doesn’t list the KeyDown event; actually, it does not contain anything starting with a K (not KeyPress or KeyUp either).
This is not so bad, since simply typing “KeyDown” by hand won’t kill me, but it is highly irritating, especially when I am dealing with objects whose members I am not familiar with.
After all, one of the uses of IntelliSense is giving you a quick overview of what Methods/Properties/Fields/etc. the object has to offer – but if it leaves out some of them semi-randomly, that point is rather moot.
(By semi-randomly I mean that, while there does not seem to be any discernable pattern for which members are left out, at least it is consistent in that it is apparently always the same ones that are missing.)
Does anyone have any idea what might be causing this phenomenon? A corrupt IntelliSense cache? Is there a way to purge that cache and force a rebuild?
You could try to delete the
.sdf and.suo files of your solution (after closing it) and then reopen it.Also make sure that all Statement Completion options are checked and ‘Hide advanced members’ is unchecked (see picture).
