What are some things in the class library you wish more people knew about or used?

module index

I'm curious if there are things in the standard class library that you find useful but not widely used.

Optional! I was reluctant at first because of the nullibility, but it's so useful.

I'm not sure this is what you were going for. I think most people know about optional and are skeptical because it's not a fix for nullability.

Don't forget its subtypes. OptionalInt, OptionalDouble etc. This avoids auto(un)boxing.

Oh wow that's great. I didn't know about those at all.

I didn't have a specific goal, but yeah I do wish more people used Optional.

My one "gripe" with Optional (and I use it lightly) is that they mean for it to only be used as a return type instead of anywhere something can be optional. It can still be used as that though, they just don't recommend it.

IMHO it should be used for parameters, as long as there is more than one optional parameter. If rather all non nullable parameters though, which is usually doable.
