Hey Michael, What did you do to IntelliSense here?
5/5/2006 - By: Todd Spatafore
I inherited a machine here at work that had ReSharper installed on it. I didn't want to have to pay for it so I removed it. That was in February. Since then I haven't had any IntelliSense in Visual Studio.NET 2003. Being the piss poor programmer that I am, I rely too heavily on IntelliSense and I've been lost since then. However, I finally got frustrated today when I was trying to work with a DataGrid and I decided to do some heavy searching for a solution. The answer came rather quickly from the JetBrains web site (they made ReSharper).
The answer is this (takes directly from this address: http://support.jetbrains.com/kb/entry.jspa?categoryID=28&externalID=141):
Sometimes when uninstalling ReSharper, it fails to restore original Visual Studio's intellisense. To restore it, go to Tools > Options > Text Editor > C# > General and check "Auto list members" and "Parameter information" checkboxes.
Now I have my IntelliSense back.
