You're going to laugh, but we've discovered that the more tool windows you have open, the slower VS operates.  Most of the tool windows tie into VS IDE events and update any time the code/designer changes.  If you have any sort of refactoring tool (like DevEx Refactor!), you might try uninstalling it; we've had some of those tank before, too.  Also, with VB.NET, since it has the design-time compiler, it helps if you keep your solution size small.  The bigger the solution, the more VS has to try and compile each time the code changes.  Just a few suggestions...

Visual Studio has gotten very slow recently. It takes approximately 30s to more than a minute after a select a control before VS is ready to let me do anything. As you can imagine, this has tanked my productivity. I've taken to directly modifying the designer file, because that is way faster. I'm also getting an error every time I close VS.



It definitely seems to be a size issue. The form I'm working on is large and complex (~180 controls/components). On smaller forms it's not a problem.



I've done a repair on VS (reinstalled and then reapplied SP1). It helped for about 30 minutes.



Any ideas on how to fix this?



Thanks!
