Question

I have just installed Godot on my Linux machine (Opensuse Tumbleweed).
When I try to run my project with a .net solution inside, I get a popup saying failed to build project.

The whole error message:

I believe Godot only supports dotnet 8 right now, try to install dotnet 8 sdk instead and see if that helps.

You are correct, I thought I only had dotnet 9 on my Windows computer, but I am wrong. I have both dotnet 9 and 8 on my Windows computer.

I installed dotnet 9 on my linux machine and it works.
