[Tracking] The repo needs clear rules for use of "see cref" and "see langword" attributes

[paul1956]

Inconsistent use of the "see cref" attribute.

1. It is used for every occurrence where it could be used (all places VS has a code fix), including summary and return/value sections. This really clutters the documentation.
2. It is used once in summary and not in return/value where it could be used also.
3. It is used in return/value but not in summary where it could be.
4. It is not used at all typically where the target is not fully qualified, so VS will not offer a CodeFix but there are also times it will and it isn't used.

Inconsistent use of the "see langword" attribute.

1. It is seldomly used where it could be. true/True, false/False, null/Nothing, Property, Event, I don't know the full list but the CodeFix does.

Guideline would be great; I am not suggesting anyone has to go back and fix everything especially without a CodeAnalyzer (unless it was standalone it would be horribly slow and would produce too may incorrect results) but as code is touched it would be nice to have consistent rules.
