Hi, and welcome!
Please see the FAQ: What's a reproducible example (`reprex`) and how do I create one? Using a reprex, complete with representative data will attract quicker and more answers. *This question of course isn't coding related so it doesn't require one.
Whenever I venture into Windowlands I risk getting caught out, but maybe living in a town that borders Redmond, WA, I'll be ok this time.
RStudio is an interface to R and, accordingly, depends on it to work at all.
There are some packages with dependencies on OS system packages. The most obvious is the rJava package. I don't know of any related to .net, but then as a *nix guy I wouldn't be looking.
