It’s supposed to work (like, it’s an option in Rider’s project selection), but it can’t find MSBuild in the WSL. I’m guessing you’d have better luck if you just spun up a normal Linux VM though.
I found the performance very poor and had to discontinue using it.
It permanently pinned 4 cores on the remote server where VS Code used <0.25 (codebase was a very small Django app)
I'll admit I haven't looked recently, but last time I looked, it felt like Jetbrains didn't quite get my use cases for remote development. I don't want to install/manage any infrastructure at all. I just want to connect via ssh to a fresh box and have it work. If that isn't possible, back to the drawing board.
