DescriptionAttribute vs.

tag for Properties

I'm writing a Class Library in C# under VS 2005 (I know, get with modern times, but we're on a tight budget here).

It appears to me that if I use a "summary" tag in the XML documentation, my users can see that info via Intellisense and tooltips, etc., but not in the Properties window in Studio.

To get something in that window, I seem to need to use a [Description("This is it")] attribute.

Am I correct on this? If so, then it would seem that I need to duplicate the description info :-(

Or, is there a better way? Thanks!
