Yes, I'm using C#.
Hmm, possibly a bug, then?
If you have VS.NET 2003, do this with 1645 or later:
Create a new class library project. Go to the newly created class file. Inside the class begin typing a line such as:
public Hashtable whatever;
It will bring up a a suggestion list when you start typing hashtable, suggesting the variable. I usually hit the tab key at this point to finish it. On 1640 it brings up a second suggestion list containing the using statement, the Icon next to it looks like a the icon for a VA Snippet. On later builds, it brings up a second list, but it contains only the entry for Hashtable by itself, no suggestion for System.Collections.Hashtable, and no suggestion for using System.Collections.
