For the past few weeks I’ve been trying out unity 2019.2.0b9 and I have found that unity doesn’t automatically recognise rider on my Ubuntu 18.04.3 machine. I have to go to preferences --> external tools --> external script editor to manually add it. Once I have set it there, you may think it should work from there whenever you create a new project but no, I have to set it up every single time for a new project and this is annoying. I installed rider using the Ubuntu Software store. If anyone has a solution that would be great or if anyone knows if this has been fixed in the latest revision, then great.
Please report it if you can reproduce it.
For Unity 2019.2+ Rider package is needed.
