Using Resharper -- is it really a "personal decision"?

Question

My team lead recommends that all the developers user ReSharper but he does not "enforce" this recommendation. As a result, whenever I open some code it immediately jumps out to me whether the developer who wrote it used ReSharper or not. Tell-tale signs are unnecessary nesting, use of redundant type declarations and generic parameters, typos in symbol names (because it would be too hard for them to fix them), etc.

The unstated assumption seems to be that the user of ReSharper is a "personal decision" that does not affect anyone else. But is this really true? What level of "enforcement" on this issue is ideal?

Answer 1

If you work in a group, then nothing that affects your code is purely a personal decision.

I think the use of tools like ReSharper should be determined the same way style conventions are implemented. Everyone does it. Or no-one does it.

It's really annoying as a developer having hundreds of warnings from other developers who just didn't write to the same standards as everyone else.
