Also what's the problem with VS Code? It's great for C#, and basically the mainstream choice for many other stacks like Go and Node already.
As long as you have a small number of total VSC users (not just on a team/project, but in an org; ≤5), and are in a small, luddite, or mostly-tablets org (≤250 PCs), and don’t have much money coming through (≤$1 million revenue.)
Otherwise, its only usable for open source work, academic research, and classroom training.
ReSharper isn't really needed although nice to have and actually not expensive. It costs less than a decent toolbox for a handyman.
VS is nice, and one of the better IDEs but by comparison it is wildly overpriced.
I would be hesitant to join a company that isn't even willing to pay for vs professional.
The cutoff for Community is >5 VS Community users (not developers, either, as VS is also intended for testers, etc.), not 250, or >250 PCs in the org (not “developers” or “using VS Community”, just PCs existing in the org.)
At any rate, I've never found even the free Visual Studio Community to feel like a "basic editor."
