Rider? https://www.jetbrains.com/rider/
edit: https://github.com/OmniSharp exists, and is LSP-ish, but I have never used it.

It's been years since I've used Resharper and maybe things have changed, but if you are looking to improve battery life, it's one of the last things I would start using.
My work laptop is often at full ram usage (16mb) with the fans spinning at full speed.
I used to code in vim and sublime text. The change in system load is shocking. I like Rider and will continue to use it but it's crazy how much of a hog it is.
At least you've upgraded beyond 640k!
