Description

For objects like DateTime or Int32 there's a known list of supported format strings, such as "s" for DateTime or "N0" for Int32. It'd be really helpful if IntelliSense knew about these and gave auto completion for them.

Outside of the few I use regularly I always have to refer back to the docs to see what the available options are along with the resulting output. What I'd like to see is a list of values such as: o - 2018-09-10T20:44:10.3523872-04:00 s - 2018-09-10T20:44:10
