what is the simplest way to cache how many users enabled？

[scil]

I want to display user count on admin dashboard. Is there any simple way to fetch and cache the number?

I want to use microsoft memorycache, do i need to implement it on my own? is there any methods available in OC?

You consider to use cache TagHelper in Razor View

Thank you. I serve use count as an API, razor tag useless for me.

And I'd like to know how to update my cahce when a user added or deleted.
