Q:

Should the canonical Q&A on NullReferenceExceptions tag common .NET languages?

I like the canonical Q&A on a NullReferenceException. I like it a lot. I like it so much that I want to use it to close questions on the topic of NRE's. 
Except, since it is not tagged as c# (at least, that's why I assume this is), it does not get picked up by the search inside the close-as-duplicate window (searching for nullreference and nullreferenceexception).
When looking at the revision history I notice that the tag has been added and removed several times already.
Why do some members of the community not want that tag in there?
I assume this is done to keep it general and just stick to the .net tag? Nevertheless I believe tagging the most relevant .NET languages would be a good way to go.

A:

It shouldn't be tagged with c# because it is not a C# specific feature, it is a 'feature' or component of the .Net framework.
