On Stack Overflow, the asp tag was made a synonym of asp-classic since that is generally what is meant. Looking over the 8 that are were tagged here as asp shows a similar pattern of usage. (though I should add that most weeks we still end up with a dozen or so that meant asp.net...)
This was done as most of the time asp was being used by people who were unaware that there were two different technologies that that tag was referring to.
Here's some of the related discussion from the main Meta.SO:
- Classic Re-Tag Discussion on some good ole ASP (Classic)
- Let's Ban the [ASP] Tag on StackOverflow!
- Where'd the [asp] tag go, and why did it come back?
I would suggest making a similar change here and removing all the asp and changing to asp-classic or asp.net as appropriate. And maybe borrowing the text from the tag wiki for asp-classic and asp.net.
I'd fix it, but I'm a little short on the rep requirement... I did some suggested edits/flags for the 6 that were there.
