Godot Version

Godot_v4.3-stable_mono_win64

Question

So I am switching from Unity to Godot for my game and I am trying to follow xen-42’s ‘mini solar system in Godot 4 C#’ tutorial but when I attach the script to something it say’s in the inspector “this inspector might be out of date. Please build the C# project” my project has a C# solution and I have .Net installed (V8), also, when playing the scene it doesn’t run, just saying “Building .Net project” with a loading bar that isn’t increasing from 0% before just saying “failed to build project” I have looked everywhere but I couldn’t find an answer anywhere!

here is the screenshot from my MSBuild console and it has 68 errors, I made a seperate test project, put a C# script on a game object and it was successfull! I think the problem might be the version, I’ll try download the version that the tutorial uses and reply if it works!

Ok, so it was the editor that was the problem, I have switched to the editor used in the tutorial, Godot 4.2.1.
