What happened here?

1175 new c#3.0 questions
(source: tejp.de)

Was it a retag? (I couldn't find any [retag-request] about this.)

If it's the result of a retag, shouldn't the tag rather be [c#-3.0]? This format seems to have become the canonical "language version" format (see the existing tag synonyms).

On the other hand, the other C# version tags like [c#2.0]) also don't contain a hyphen.

Should the tags for special C# versions be hyphened, or not? Is [c#x.0] preferable, or should [c#-x.0] be used, which would be consistent with other languages?

  • Hm... there seem to be whole buckets of oddities in tag creation these days...

C#3.0 should exist as a tag. There are features that are specific to C# 3.0 like LINQ and anonymous object initialization.

It should be whatever the convention for language version tags is. If it's C#-x.0 then so be it.

  • I don't think this was ever in question, it was just whether or not a - should be part of the tag Commented Jul 21, 2010 at 4:18
  • The title of the question is 'should it exist'? Thats'w here I got that idea from. Commented Jul 21, 2010 at 11:08
  • Ah, I see. I interpreted that as "should it exist, or should it be [c#-3.0] instead", not "should it exist, or should all c# questions be under one tag" Commented Jul 21, 2010 at 18:06

I don't think it's new. I was going to file a retag request a few days ago to go the other way ([c#x] to [c#-x]), but there are already tag synonyms to do so, they just aren't applied retroactively. I didn't exactly follow why that is, but I suspect when they finish implementing tag synonyms they're going to apply them to all the old posts in a mass retag

  • I don't see any such tag synonyms on stackoverflow.com/tags/synonyms

  • I blew off the synonym it was the wrong way around
