I’m sure you can point to many things Rider is better at, but I’ve found enough sharp edges (including, annoyingly, it not being able to infer types that Roslyn can) that it’s not a sell for me. It’s also much faster and supports NCrunch.
Never heard of ncrunch but I googled it and its described as
> the ultimate live testing tool for Microsoft Visual Studio and JetBrains Rider
So it seems at least that part of your critique is outdated.
I'm not sure what you mean about the inference, I've never had any problem with that that I can remember. And it can be a bit slow to start up or analyze a project at first load but in return it gives much better code completion and such.
