After uninstalling JetBrains’ ReSharper tool I found that Intellisense wasn’t working and after a little digging around found that it was turned off in the Microsoft Visual Studio 2008 options.

The ReSharper tool does not reinstate those options when it uninstalls (I am assuming it turns those options off when installed to disable native VS Intellisense and provide its own).

Solution :

Navigate following path in to Microsoft Visual Studio 2005
Tools -> Options -> TextEditor -> C#
Under the “Statement Completion” option I ticked the two boxes: “Auto list members” and “Parameter Information”.
