.net has an impressive wiki, but no where does it actually say what it is to be used for.
I most often see this tag used in conjunction with one of the .Net languages or in lieu of one. It doesn't seem to serve a purpose at all, because we all know that c#, vb.net, and f# all run on top of the .Net framework. The tag adds no value or information in this way.
The only legitimate reason I can think of to use the tag, would be for questions containing code from the recently open sourced framework itself. Perhaps someone wants to get their code reviewed here before submitting a pull request to the repository. I would think that will be an exceedingly rare occasion though.
So, am I missing something? Is there a legitimate reason for this tag to exist? If so, how should we be using it and what (if anything) should we do about cleaning up the tag?
